Abstract:
Variometric Approach for Standalone Engine Displacement Analysis (VADASE) is a technique used in seismology purposes using GPS measurements. VADASE is used to determine the small displacement from the earthquake. The VADASE L1 solution is using the klobuchar ionospheric model. In this study VADASE was used in earthquakes with magnitudes> 7 to> 9 righter scales. In the scale of the earthquake category> 9 used Indian Ocean earthquake of December 26, 2016 with the strength of 9.1 SR by using the closest SAMP station and the Japanese Tohoku earthquake of March 11, 2011 with a power of 9.1 SR using 4 different stations namely MIZU, KMSV, TSK2 and Knii . The earthquake category with a scale of> 8 SR is the offshore earthquake Bio Bio, Chile on February 27, 2010 with a power of 8.8 SR using 2 stations namely ANTC and SANT, the Bengkulu Indonesia earthquake on 12 September 2007 with a power of 8.4 SR using the SAMP station, an illaper earthquake, chile September 16 2015 with 8.3 SR using SANT station, and Tres Piscos earthquake Mexico on September 8, 2017 with a power of 8.2 SR using IENG station. Earthquake with a strength of> 7 SR, namely the amberlay-New Zealand earthquake on November 13, 2016 with a strength of 7.8 SR using MRLL and WGTN stations, Puerto quello-chile earthquake on December 25, 2016 with a strength of 7.6 SR using COYQ station, Java sea earthquake -Indonesia on 8 August 2007 with 7.5 SR power using BAKO station and ayula mexico earthquake on 19 september 2017 with 7.1 SR power using INEG station. From the results of VADASE, the farthest distance from the epicenter to the observation station is 1100 km (INEG station) and the closest distance is 95 km (BAKO station). The highest speed is 0.12 m / s after 5 minutes from the earthquake in the earthquake Offshore Bio Bio-Chile 2010 uses the SANT station and the lowest speed is 0.006 m / s after 10 minutes from the earthquake in the 2007 Bengkulu earthquake using the SAMP station. Whereas in the other earthquakes was the 2011 Tohoku earthquake with a speed of 0.06 m / s after 1 minute using MIZU station, the amberley-New Zealand earthquake 2016 with a speed of 0.015 m / s after 1 minute using the MRLI satellite, Puerto quelloearthquake Chile 2016 with a speed of 0.025 m / s after 40 minutes using the COYQ satellite.

Abstract. The mechanical description of the seismic cycle has an energetic analogy in terms of statistical physics and the second law of thermodynamics. In this context, an earthquake can be considered a phase transition, where continuous reorganization of stresses and forces reflects an evolution from equilibrium to non-equilibrium states, and we can use this analogy to characterize the earthquake hazard of a region. In this study, we used 8 years (2007–2014) of high-quality Integrated Plate Boundary Observatory Chile (IPOC) seismic data for > 100 000 earthquakes in northern Chile to test the theory that Shannon entropy, H, is an indicator of the equilibrium state of a seismically active region. We confirmed increasing H reflects the irreversible transition of a system and is linked to the occurrence of large earthquakes. Using variation in H, we could detect major earthquakes and their foreshocks and aftershocks, including the 2007 Mw 7.8 Tocopilla earthquake, the 2014 Mw 8.1 Iquique earthquake, and the 2010 and 2011 Calama earthquakes (Mw 6.6 and 6.8, respectively). Moreover, we identified possible periodic seismic behaviour between 80 and 160 km depth.

Abstract:
SUMMARY We recently found the original Omori seismograms recorded at Hongo, Tokyo, of the 1922 Atacama, Chile, earthquake (MS = 8.3) in the historical seismogram archive of the Earthquake Research Institute (ERI) of the University of Tokyo. These recordings enable a quantitative investigation of long-period seismic radiation from the 1922 earthquake. We document and provide interpretation of these seismograms together with a few other seismograms from Mizusawa, Japan, Uppsala, Sweden, Strasbourg, France, Zi-ka-wei, China and De Bilt, Netherlands. The 1922 event is of significant historical interest concerning the cause of tsunami, discovery of G wave, and study of various seismic phase and first-motion data. Also, because of its spatial proximity to the 1943, 1995 and 2015 great earthquakes in Chile, the 1922 event provides useful information on similarity and variability of great earthquakes on a subduction-zone boundary. The 1922 source region, having previously ruptured in 1796 and 1819, is considered to have significant seismic hazard. The focus of this paper is to document the 1922 seismograms so that they can be used for further seismological studies on global subduction zones. Since the instrument constants of the Omori seismographs were only incompletely documented, we estimate them using the waveforms of the observed records, a calibration pulse recorded on the seismogram and the waveforms of better calibrated Uppsala Wiechert seismograms. Comparison of the Hongo Omori seismograms with those of the 1995 Antofagasta, Chile, earthquake (Mw = 8.0) and the 2015 Illapel, Chile, earthquake (Mw = 8.3) suggests that the 1922 event is similar to the 1995 and 2015 events in mechanism (i.e. on the plate boundary megathrust) and rupture characteristics (i.e. not a tsunami earthquake) with Mw = 8.6 ± 0.25. However, the initial fine scale rupture process varies significantly from event to event. The G1 and G2, and R1 and R2 of the 1922 event are comparable in amplitude, suggesting a bilateral rupture, which is uncommon for large megathrust earthquakes.

Abstract:
Abstract We investigated the temporal variation of the mechanism of large intraplate earthquakes at intermediate depths in relation to the occurrence of large under-thrusting earthquakes in Chile. Focal mechanisms were determined for three large events (1 March 1934: M = 7.1, d = 120 km; 20 April 1949: M = 7.3, d = 70 km; and 8 May 1971: MW = 7.2, d = 150 km) which occurred down-dip of the great 1960 Chilean earthquake (MW = 9.5) rupture zone. The 1971 event is down-dip compressional: θ (strike) = 12°, δ (dip) = 80°, and λ (rake) = 100°. The 1949 earthquake focal mechanisms is θ = 350°, δ = 70°, and λ = −130°. The data available for the 1934 event are consistent with a down-dip tensional mechanism. Thus, the two events which occurred prior to the great 1960 Chilean earthquake are down-dip tensional. Published fault plane solutions of large intermediate-depth earthquakes (28 March 1965 and 7 November 1981) which occurred down-dip of the Valparaiso earthquakes of 1971 (MW = 7.8) and 1985 (MW = 8.0) are also down-dip tensional. These results suggest that before a major thrust earthquake, the interplate boundary is strongly coupled, and the subducted slab is under tension at intermediate depths; after the occurrence of an interplate thrust event, the displacement on the thrust boundary induces transient compressional stress at intermediate depth in the down-going slab. This interpretation is consistent with the hypothesis that temporal variations of focal mechanisms of outer-rise events are due to changes of interplate coupling.

Abstract:
Abstract. More than half of all the people in the world now live in dense urban centres. The rapid expansion of cities, particularly in low-income nations, has enabled the economic and social development of millions of people. However, many of these cities are located near active tectonic faults that have not produced an earthquake in recent memory, raising the risk of losing hard-earned progress through a devastating earthquake. In this paper we explore the possible impact that earthquakes can have on the city of Santiago in Chile from various potential near-field and distant earthquake sources. We use high-resolution stereo satellite imagery and imagery-derived digital elevation models to accurately map the trace of the San Ramón Fault, a recently recognised active fault located along the eastern margins of the city. We use scenario-based seismic-risk analysis to compare and contrast the estimated damage and losses to the city from several potential earthquake sources and one past event, comprising (i) rupture of the San Ramón Fault, (ii) a hypothesised buried shallow fault beneath the centre of the city, (iii) a deep intra-slab fault, and (iv) the 2010 Mw 8.8 Maule earthquake. We find that there is a strong magnitude–distance trade-off in terms of damage and losses to the city, with smaller magnitude earthquakes in the magnitude range of 6–7.5 on more local faults producing 9 to 17 times more damage to the city and estimated fatalities compared to the great magnitude 8+ earthquakes located offshore in the subduction zone. Our calculations for this part of Chile show that unreinforced-masonry structures are the most vulnerable to these types of earthquake shaking. We identify particularly vulnerable districts, such as Ñuñoa, Santiago, and Providencia, where targeted retrofitting campaigns would be most effective at reducing potential economic and human losses. Due to the potency of near-field earthquake sources demonstrated here, our work highlights the importance of also identifying and considering proximal minor active faults for cities in seismic zones globally in addition to the more major and distant large fault zones that are typically focussed on in the assessment of hazard.

Abstract:
Purpose – The purpose of the present paper is to explore the political discourse present in the show Chile Ayuda a Chile [Chile helps Chile] to support the survivors and victims of the last earthquake hit Chile in 2010. Based on the belief that nationalism plays a vital role in cementing the process of recovery by making survivors believe that they, after all, have a new opportunity to be on feet again. Design/methodology/approach – The visual methodology (enrooted in the analysis of content) is the chosen technique to develop five indicators which replicates the nationalist sentiment of Chileans post-disaster context. The archetype of nationalism is activated whenever the community is in danger. Findings – As Baudrillard put it, the post-modernity is witness of a much wider nation-state’s declination. Nonetheless, current information presented in this report very well contrasts a thesis of this caliber. Far-away of being experiencing a decrease of Nationalism, we argue that in contexts of emergency and chaos, nationality plays an important role to maintain a firm bondage and prevent social fragmentation. Five indicators are found in the discourse of Chile helps Chile, beautiness, sport, coercion, stratification and materiality. Research limitations/implications – The outcome of this research, because of its qualitative nature, does not allows statistical or broader inferences. For this, further investigation is needed. Originality/value – Much of disaster-related texts have been influenced by Jean Baudrillard and his thesis of nation state decline. The originality of this research shows the opposite. As a process of resiliency, the national being still plays a crucial role in revitalizing the social tenets of community in context of uncertainness.

Abstract:
Studies using spaceborne interferometric synthetic aperture radar (InSAR) analysis showed that two megathrust earthquakes – the 2011Mw9.0 Tohoku-oki earthquake in Japan and the 2010Mw8.8Maule earthquake in Chile – triggered unprecedented subsidence in multiple volcanoes. There are strong similarities in the characteristics of the surface deformation in Japan and Chile: (1) Maximum subsidence is about 15 cm. (2) Areas of subsidence are elliptically elongated in a north-south direction perpendicular to the principal axis of the extensional stress change. (3) Most of this subsidence is coseismic. These similarities imply that volcanic subsidence triggered by the megathrust earthquakes is a ubiquitous phenomenon. Nonetheless, the mechanism of subsidence is yet to be investigated. Two main hypotheses have been proposed thus far: 1) The localized deformation of hot and weak plutonic bodies. 2) Water release from large hydrothermal reservoirs beneath the volcanoes.

Abstract:
A lack of comprehensive understanding of the seismic hazards associated with a subduction zone can lead to inadequate anticipation of earthquakes and tsunami magnitudes. Four hundred and fifty years of Chilean historical documents record the effects of numerous great earthquakes; however, with recurrence intervals between the largest megathrust earthquakes approaching 300 years, seismic hazard assessment requires longer chronologies. This thesis seeks to verify and extend historical records in south central Chile using a relative sea-level approach to palaeoseismology, developed in Alaska and the Pacific Northwest. Quantitative, diatom-based approaches to relative sea-level reconstruction are successful in reconstructing the magnitude of coseismic deformation during recent, well documented Chilean earthquakes. Disparities between my estimates and independent data highlight the possibility of shaking-induced sediment consolidation of tidal marshes. Following this encouraging confirmation of the approach, I quantify land-level changes in longer sedimentary records from the centre of the 1960 rupture zone. Here, laterally extensive marsh soils abruptly overlain by low intertidal sediments attest to the occurrence of four megathrust earthquakes. Field sites preserve evidence of the 1960 and 1575 earthquakes and Bayesian age-depth modelling constrains the timing of two predecessors to 1270 to 1410 and 1050 to 1200. The sediments and biostratigraphy lack evidence for the historically documented 1737 and 1837 earthquakes. The distribution of documented effects of these ruptures and the new palaeoseismic data presented in this thesis suggests these earthquakes were smaller in magnitude and located in the southern portion of the 1960 rupture segment, as other authors have previously inferred. Coastal sediments record relative sea-level changes reflecting both the earthquake deformation cycle and non-seismic processes. The 1000 year record of net relative sea-level rise implied by the new records presented here differs from the mid to late Holocene relative sea-level fall inferred from previous field studies and modelling approaches.

Abstract:
No Chile, país de terremotos, a surpresa foi total quando multitudinários saques a estabelecimentos comerciais começaram logo depois do megassismo que atingiu, na madrugada de sábado 27 de fevereiro de 2010, Concepción, a terceira maior área metropolitana do país. Organizaram-se nos bairros estratégias de autodefesa por temor aos rumores sobre a chegada de saqueadores. Para se restabelecer a ordem social, foi decretado Estado de Exceção. Este estudo exploratório e qualitativo busca enxergar a relação entre terremoto, violência coletiva e insegurança urbana com base nos depoimentos de homens e mulheres que entrevistamos em Concepción dois anos depois do cataclismo. Inspirados no debate teórico sobre a memória coletiva, analisaremos os silêncios e olvidos que fazem parte dos testemunhos; assim, iremos interrogar o caráter inédito que os entrevistados, mas também acadêmicos e autoridades, outorgaram aos saques pós-terremoto, que, como iremos ver, foram interpretados como sintoma do deterioramento moral da sociedade chilena sob o regime neoliberal. Por intermédio de diferentes registros do passado, buscaremos rastros sobre conflitos sociais e políticos em outros momentos da história telúrica nacional. Sobre os episódios de 2010 em específico, e seguindo os trabalhos de Charles Tilly e Javier Auyero, apresentamos numa escala microespacial alvos, dinâmicas e repertórios dos saques conforme as rememorações dos consultados, entre eles, donos de lojas vitimizados pela multidão. Por fim, para indagar o deslocamento do medo do terremoto ao medo dos outros, chamaremos a atenção sobre os modos pelos quais são representados diferentes bairros da cidade e o papel dos rumores.
Chileans, a population used to earthquakes, woke up with surprise in the morning of February 27th, 2010 since right after the earthquake that hit Concepción, the third largest metropolitan area in the country, massive looting to stores came about. Fed by rumors about roving mobs, Concepcion residents formed their own neighborhood defense squads to guard their homes, whereas the Chilean government declared State of Exception to restore the social order. Drawing on testimonies of men and women I interviewed in Concepción two years after the disaster, this exploratory and qualitative research examines the relationship between earthquake, collective violence, and urban insecurity. Following a theoretical discussion about collective memories, I explore how silence and forgetting are active elements in the process of collective remembering. In addition, this project analyzes the sense of exceptionality that my interviewees, other scholars, and state authorities have assigned to looting in the aftermath of the earthquake; events that, as I shall demonstrate, were interpreted as a symptom of moral decadence of Chilean society under the neoliberal regime. By scrutinizing historical data about past earthquakes, I look at traces of social and political conflicts associated with the occurrence of natural disaster like the one I describe here. Concerning the 2010 facts, I make use of the framework offered by Charles Tilly and Javier Auyero to present, at a micro-scale level, looting targets, dynamics and repertoires based on narratives collected empirically (among them, testimonies of storeowners who were victimized by the crowd). Finally, to explore the displacement of fearin particular, from the fear to earthquake to the fear of the othersI point out the need to pay attention to the ways in which different neighborhoods are conceived of as well as the role of rumors.

Abstract:
The seismogenic zone of subduction margins has the potential to generate some of the world’s largest earthquakes. A detailed study of the 2010 Mw 8.8 Maule, Chile rupture has enabled interpretation of the controls that govern subduction zone seismic behaviour across the earthquake cycle. In this thesis, we focus on two aspects of the central Chile margin: (1) imaging physical properties in the forearc and along the plate interface; (2) assessing source complexity of megathrust ruptures. We exploit a dataset of seismic body wave onset times from local aftershocks recorded on a temporary network to derive a 3-D seismic velocity model of the Maule rupture area. We image the main domains of the subduction zone and find a high velocity anomaly located along the plate interface, which we initially interpret as a subducted topographic high. We then develop a second, more accurate velocity model that uses an improved arrival time dataset together with observations from ocean-bottom seismometers. This refined model gives a sharper view of both the plate interface close to the trench, and the marine forearc. We show that ancient blocks of dense mantle in the lower forearc may have decelerated slip during the Maule earthquake and contributed to its nucleation. Furthermore, we infer that fluid saturated sediments inhibited significant slip close to the trench. We study source processes of a large aftershock of the Maule sequence, the 2011 Mw 7.1 Araucania earthquake, by inverting local seismic waveforms for a multiple point-source faulting solution. We find this earthquake constituted rupture on the plate interface followed by almost instantaneous slip along a normal fault in the overriding plate: the first observation of its kind. The second rupture of this closely-spaced doublet was hidden from teleseismic faulting solutions, and may have been dynamically triggered by S-waves from the first event. Overall, our work highlights the role played by the upper plate in subduction zone seismogenesis. We suggest that seismic velocities can help to characterise the behaviour of future large megathrust earthquakes. We show that the potential hazard posed by closely-spaced doublets involving the upper plate should be accounted for in real-time tsunami warning systems by using local waveform analysis.

Abstract:
Logging and large earthquakes are disturbances that may significantly affect hydrological and erosional processes and process rates, although in decisively different ways. Despite numerous studies that have documented the impacts of both deforestation and earthquakes on water and sediment fluxes, a number of details regarding the timing and type of de- and reforestation; seismic impacts on subsurface water fluxes; or the overall geomorphic work involved have remained unresolved. The main objective of this thesis is to address these shortcomings and to better understand and compare the hydrological and erosional process responses to such natural and man-made disturbances. To this end, south-central Chile provides an excellent natural laboratory owing to its high seismicity and the ongoing conversion of land into highly productive plantation forests. In this dissertation I combine paired catchment experiments, data analysis techniques, and physics-based modelling to investigate: 1) the effect of plantation forests on water resources, 2) the source and sink behavior of timber harvest areas in terms of overland flow generation and sediment fluxes, 3) geomorphic work and its efficiency as a function of seasonal logging, 4) possible hydrologic responses of the saturated zone to the 2010 Maule earthquake and 5) responses of the vadose zone to this earthquake. Re 1) In order to quantify the hydrologic impact of plantation forests, it is fundamental to first establish their water balances. I show that tree species is not significant in this regard, i.e. Pinus radiata and Eucalyptus globulus do not trigger any decisive different hydrologic response. Instead, water consumption is more sensitive to soil-water supply for the local hydro-climatic conditions. Re 2) Contradictory opinions exist about whether timber harvest areas (THA) generate or capture overland flow and sediment. Although THAs contribute significantly to hydrology and sediment transport because of their spatial extent, little is known about the hydrological and erosional processes occurring on them. I show that THAs may act as both sources and sinks for overland flow, which in turn intensifies surface erosion. Above a rainfall intensity of ~20 mm/h, which corresponds to <10% of all rainfall, THAs may generate runoff whereas below that threshold they remain sinks. The overall contribution of Hortonian runoff is thus secondary considering the local rainfall regime. The bulk of both runoff and sediment is generated by Dunne, saturation excess, overland flow. I also show that logging may increase infiltrability on THAs which may cause an initial decrease in streamflow followed by an increase after the groundwater storage has been refilled. Re 3) I present changes in frequency-magnitude distributions following seasonal logging by applying Quantile Regression Forests at hitherto unprecedented detail. It is clearly the season that controls the hydro-geomorphic work efficiency of clear cutting. Logging, particularly dry seasonal logging, caused a shift of work efficiency towards less flashy and mere but more frequent moderate rainfall-runoff events. The sediment transport is dominated by Dunne overland flow which is consistent with physics-based modelling using WASA-SED. Re 4) It is well accepted that earthquakes may affect hydrological processes in the saturated zone. Assuming such flow conditions, consolidation of saturated saprolitic material is one possible response. Consolidation raises the hydraulic gradients which may explain the observed increase in discharge following earthquakes. By doing so, squeezed water saturates the soil which in turn increases the water accessible for plant transpiration. Post-seismic enhanced transpiration is reflected in the intensification of diurnal cycling. Re 5) Assuming unsaturated conditions, I present the first evidence that the vadose zone may also respond to seismic waves by releasing pore water which in turn feeds groundwater reservoirs. By doing so, water tables along the valley bottoms are elevated thus providing additional water resources to the riparian vegetation. By inverse modelling, the transient increase in transpiration is found to be 30-60%. Based on the data available, both hypotheses, are not testable. Finally, when comparing the hydrological and erosional effects of the Maule earthquake with the impact of planting exotic plantation forests, the overall observed earthquake effects are comparably small, and limited to short time scales.
Landmanagement und tektonische Prozesse haben einen erheblichen Einfluss auf das Abflussverhalten und den Wasser-, sowie den Sedimenthaushalt von Gebirgsregionen. Sowohl forstwirtschaftliche Bewirtschaftung, als auch starke Erdbeben sind Impulse, die hydrologische und Erosionsprozesse, sowie deren Prozessraten beeinflussen. Obwohl zahlreiche Arbeiten bereits den Einfluss von forstlicher Bewirtschaftung (Abholzungen, Aufforstungen) als auch von Erdbeben auf Wasser und Sedimentflüsse dokumentiert haben, bleiben wichtige Fragen offen. Wie entscheidend ist der Zeitpunkts der Abholzung und des nachfolgenden Wiederaufforstens? Wie wirken seismische Störungen auf unterirdische Wasserflüsse? Wie ändert sich die geomorphologische Arbeit nach Kahlschlägen? Zur Erforschung dieser Fragen bietet sich das südliche Zentralchile aufgrund seiner hohen lokalen seismischen Aktivität und der kontinuierlichen Umwidmung von Flächen in hochproduktive Plantagenwälder hervorragend an. Letztere verursachen sich häufig verändernde Umweltbedingungen durch kurze forstwirtschaftliche Rotationszyklen. Diese Dissertation betrachtet Einzugsgebiete mit vergleichbarer naturräumlicher Ausstattung. Dabei werden experimentelle Datenerhebung, ein Monitoring-Programm und Datenanalysetechniken mit prozessbasierter Modellierung kombiniert. Ziel der vorliegenden Arbeit ist: 1) die Untersuchung des Einflusses von Plantagenwäldern auf den lokalen Wasserhaushalt. Hier zeigt sich, dass die Baumart (Pinus radiata vs. Eucalyptus globulus) keinen entscheidenden Einfluss auf die lokale Wasserbilanz hat. Vielmehr ist der Bodenwasserspeicher unter dem gegebenen lokalen Hydroklima der entscheidende Faktor für den Wasserverbrauch. 2) die Untersuchung des Verhaltens von Kahlschlagflächen im Hinblick auf Quellen oder Senkenwirkung für Oberflächenabfluss und Sedimenttransport. Hier zeigt sich, dass diese Flächen sowohl als Quelle als auch als Senke für Oberflächenabfluss und Sedimenttransport wirken können – abhängig von der Regenintensität. Übersteigt diese ~20 mm/h, was <10 % der lokalen Niederschlagsereignisse entspricht, generieren Kahlschlagflächen Horton-Oberflächenabfluss (Infiltrationsüberschuss) und Sedimenttransport. Unterhalb dieses Schwellenwerts wirken sie als Senke. In Anbetracht der lokalen Niederschlagintensitäten ist der Gesamtbeitrag des Horton-Oberflächenabflusses daher sekundär. Der Großteil des Abflusses entsteht durch Dunne-Oberflächenabfluss (Sättigungsüberschuss). Zudem zeigt die vorliegende Arbeit, dass Abholzen die Infiltrabilität erhöhen kann. Dies führte dazu, dass zunächst der Gebietsabfluss abfällt bevor er erst nach Auffüllen des Grundwasserspeichers signifikant ansteigt. 3) Die Untersuchung des Einflusses von Kahlschlägen auf die hydro-geomorphologische Arbeit und ihre Effizienz. Durch das Anwenden von Quantile Regression Forests (QRF) wird auf kurzer Prozessskala gezeigt, dass Abholzung zu unterschiedlicher Jahreszeit zu signifikanten Veränderungen im Sedimenttransport führt. Vor allem Kahlschläge die während der Trockenzeit durchgeführt werden, verursachten einen Bedeutungsverlust von seltenen, stärkeren Abflussereignissen zu Gunsten der häufigeren, jedoch weniger starken Ereignissen. Hierbei dominierte der Dunne-Oberflächenabfluss. Dies stimmt mit den Ergebnissen eines prozessbasierten hydrologischen Modells (WASA-SED) überein. Es ist somit eindeutig die Jahreszeit, die die Leistung der hydro-geomorphologischer Arbeit nach Kahlschlägen prägte. 4) die Untersuchung von Grundwasserreaktionen auf das M8.8 Maule Erdbeben. Unter Grundwasserbedingungen kann der gesättigte Saprolith mit Verdichtung auf die Erdbebenerschütterungen reagieren. Dieser Prozess erhöht den hydraulischen Gradienten, der eine plausible Erklärung für den beobachteten Anstieg am Gebietsausfluss nach dem Erdbeben liefert. Die Verdichtung mobilisiert Grundwasser, das zudem von der ungesättigten Bodenmatrix aufgenommen werden kann. Hierdurch erhöht sich das Wasservolumen im Wurzelraum und begünstigt die Pflanzaktivität. Eine solche Aktivitätserhöhung spiegelt sich in verstärkten Tagesgängen wider. 5) die Untersuchung von hydrologischen Reaktionen auf das Erdbeben in der ungesättigten Zone. Hier zeigt sich, dass auch Bodenwasser aus der ungesättigten Bodenzone durch Erdbebenerschütterungen freigesetzt werden kann und den darunter liegenden Grundwasserspeicher zufließt. Hierdurch steigt der Grundwasserspiegel in den Talböden und erhöht dort die Pflanzenwasserverfügbarkeit. Durch inverse Modellierung wurde ein erdbebenbedingter Anstieg der Pflanzenaktivität von 30-60% quantifiziert. Beide Hypothesen sind jedoch auf Basis der verfügbaren Daten nicht eindeutig verifizierbar. Vergleicht man den Effekt des Erdbebens auf den Wasserhaushalt mit dem Effekt der exotischen Plantagenwälder zeigt sich, dass die Gesamtwirkung des Erdbebens auf den Wasserhaushalt vergleichsweise klein war und sich zudem auf kurze Zeiträume beschränkte.

Abstract:
Assessment of post-liquefaction residual strength is needed for the development of empirically-based, predictive correlations for earthquake engineering design. Previous practice commonly assigned negligible strengths to liquefied materials for engineering analysis, producing overly-conservative designs. Increasingly available case history data, and improved analytical tools have allowed for more accurate and less overly-conservative estimation of soil residual strength, improving empirical predictive models. This study provides a new case history to the limited suite of (approximately 30) liquefaction failure case histories available for post-liquefaction in-situ strength predictive correlations. This case history documents the Las Palmas gold mine tailings dam failure, resulting from seismic-induced liquefaction during the moment magnitude 8.8 February 27, 2010 Maule, Chile earthquake; the sixth largest since 1900. Forensic analysis provides reasonably well-constrained values of 1) back-calculated representative post-liquefaction residual strength, 2) representative penetration resistance, and 3) representative vertical effective stress along the suspected liquefied failure surface. This study employs the incremental momentum method to incorporate momentum effects of a moving soil mass. The incremental momentum method requires a series of cross sections animating the geometry of failure progression from initiation to termination, converging on the observed final geometry. Using interpreted soil strength characteristics, an iterative procedure approximates the back-calculated value of post-liquefaction residual strength. Findings of this case history plot well with existing empirical deterministic regression charts and are in general agreement with previous, related efforts. Results yield representative, well-constrained values of: 1) post-liquefaction residual strength ≈ 173 psf, 2) penetration resistance of N1,60,CS ≈ 5 and N1,60 ≈ 2.5, and 3) vertical effective stress ≈ 4,300 lb/ft2, or ≈ 2.0 atm.

Full text
Abstract:
Improving seismic hazard analysis is an important part of building safer structures and protecting lives. Since large magnitude earthquakes are rarer than other earthquakes, it is harder to model seismic hazards such as lateral spread displacements for these events. Engineers are often required to extrapolate current lateral spreading models when designing utilities, bridges, and piers to withstand the ground displacements caused by earthquakes with magnitudes larger than 8.0. This study uses three case histories from the Maule Chile 2010 earthquake (Mw =8.8) to develop recommendations on which models are most accurate for large earthquake events and how to improve the accuracy of the models. Six empirical models commonly used in engineering practice are compared. The model that best matches the Maule Chile case histories uses local attenuation relationships to make it easier to apply the model to any seismic region. Models that use lab data from cyclic shear tests over predict displacements but using a strain-reduction factor with depth significantly improved the accuracy of the results. Site-to-source distances can vary greatly between geographic seismic and faulting mechanisms. For this reason, models that depend on an internal source-to-site distance show less promise with large subduction zone earthquakes throughout the world. Models with site-to-source distances are most accurate in the western United States and Japan because the case histories for these models came from those countries.

Abstract:
Over the past several decades, empirical formulas have been developed and improved to predict liquefaction and lateral spread based on a database of case histories from observed earthquakes, such as Youd et al. (2002) and Rauch and Martin (2000). The 2010 Maule Chile earthquake is unique first of all because it is recent and was not used to develop recent liquefaction and lateral spread evaluation methods, and therefore can be reasonably used to evaluate the effectiveness of such equations. Additionally, the 8.8 magnitude megathrust event fills a significant gap in the databases used to develop these empirical formulas, which tends to under represent large magnitude earthquakes and events which occur along subduction zones. Use of case histories from this event will therefore effectively test the robustness and accuracy of these methods.As a part of this comparison, data will be collected from two piers in Port Coronel, Chile: Lo Rojas or Fisherman's Pier, and el Carbonero. Lo Rojas is a municipally owned pier which failed in the 2010 earthquake. Dr. Kyle Rollins gathered detailed engineering survey data defining lateral spread displacements along this pier in a reconnaissance visit with other GEER investigators after the earthquake. El Carbonero was under construction during the earthquake, but no known lateral displacements were observed. Collaboration with local universities and personnel contributed a great deal of knowledge about the soil profile. In early April 2014, collection of SPT and CPT data began in strategic locations to fill gaps of understanding about the stratigraphy near the two piers. Additional testing will provide necessary information to carry out predictions of displacements using current empirical models, which can then be compared with observed displacements collected after the earthquake. Collected data will also be complied, and this alone will provide useful information as it represents a unique case history for future evaluation.The goals of this study are therefore: (1) Collect data for two piers (Lo Rojas and el Carbonero) in Port Coronel, Chile to provide a useful case history of lateral displacements observed; (2) Conduct a liquefaction and lateral spread analysis to predict displacement of the two piers in question, considering lateral spread and slope stability; (3) Compare predicted values with observed displacements and draw conclusions on the predictive capabilities of analyzed empirical equations for similar earthquakes (4) Make recommendations to improve when possible.

Abstract:
Seismic behavior of the urban water pipelines has been considered due to its vital role, and also experiences of recent earthquakes which demonstrate poor seismic performance of mentioned pipelines. Previous experiences such as Bam (2003), Chile (2010) and Japan (2011) earthquakes indicated that urban water pipelines were out of service after earthquake and numerous problems were apparent on the post-disaster management. In this research, the water pipeline network of a zone in Tehran city was selected as a case study. The Hydraulic Failure Analysis (HFA) of the water pipelines in the proposed zone was carried out and failure potential points of the pipelines were determined. In addition, these points were investigated using orifice theory of leakage problem. Then, the proposed network was modeled using Finite Element Analysis (FEA). Also, nonlinear time-history analysis has been undertaken using three seismic scaled records of different earthquakes. Eventually, a statistical test demonstrated that there is a significant difference in the seismic performance of piping system before and after an earthquake.

Full text
Abstract:
In this study, we utilize US Geological Survey citizen science earthquake felt intensity data to investigate whether , crustal earthquakes in the Chilean Subduction Zone show similar, "felt intensity" distributions to events of the same magnitude and depths within the Cascadia Subduction Zone (Quitoriano &amp; Wald, 2020; USGS Earthquake Hazards Program, 2020). In a companion article (Rutherford &amp; Cassidy, 2022) we examine intraslab deep earthquake intensity patterns for the Chile and Cascadia subduction zones. Building on from the intraslab companion article, the goal of this comparison is to determine whether felt intensity information from several recent large (M8-8.8) subduction earthquakes in Chile can be applied to Cascadia (where no subduction earthquakes have been felt since 1700). This would provide a better understanding of shaking intensity patterns for future subduction earthquakes in Cascadia - critical information for scientists, engineers, and emergency management organizations. For this research, we utilized 20 years of cataloged Did-You-Feel-It (DYFI) citizen science data from the US Geological Survey's (USGS) earthquake online catalog, the ANSS Comprehensive Earthquake Catalog (ComCat) Documentation (USGS Earthquake Hazards Program, 2021). In total, we considered and compared intensity patterns for fourteen magnitudes from 30 earthquakes in Cascadia (ranging from magnitudes 4.5 to 7.2, the highest magnitude event in Cascadia zone) to the intensity patterns from 114 earthquakes in Chile, with the same magnitudes as the Cascadia events (M4.5-M7.2). Our analysis involved plotting and fitting the Chile and Cascadia earthquake DYFI responses to compare the intensity patterns for the two subduction zones. Overall, we find good agreement between felt patterns in Chile and Cascadia. For example, all plots show the expected downward trend for intensity with distance. Even distribution with limited clustering is seen in all fourteen magnitudes, with slight intensity clustering of responses around the 30 to 600 km. This is slightly different from the intraslab pattern which demonstrated a distinct cluster at further distance from the hypocenter, e.g., cluster at 50 to 300 km. These results provide confidence that we can use Chilean intensity data for megathrust earthquakes in Cascadia.

Full text
Abstract:
Earthquake focal mechanisms have contributed substantially to our understanding of modern tectonic stress regimes, perhaps more than any other data source. Studies generally group focal mechanisms by epicentral location to examine variations in stress across a region. However, stress variations with depth have rarely been considered, either due to data limitations or because they were believed to be negligible. This study presents 3D grids of tectonic stress tensors using existing focal mechanism catalogs from several subduction zones, including Cascadia, Japan, Nankai, Mexico, and northern Chile. We bin data into 50 x 50 x 10 km cells (north, east, vertical), with 50% overlap in all three directions. This resulted in 181380 stress inversions, with 90% of these in Japan (including Nankai). To the best of our knowledge, this is the first examination of stress changes with depth in several of these regions. The resulting maps and cross-sections of stress can help distinguish locked and creeping segments of the plate interface. Similarly, by dividing the focal mechanism catalog in northern Japan into those before and those &amp;gt;6 months after the 2011 Mw 9.1 Tohoku-Oki earthquake, we are able to produce detailed 3D maps of stress rotation, which is close to 90° near the areas of highest slip. These results could inform geodynamic rupture models of future megathrust earthquakes in order to more accurately estimate slip, shaking, and seismic hazard. Southern Cascadia and Nankai appear to have sharp stress discontinuities at ~20 km depth, and northern Cascadia may have a similar discontinuity at ~30 km depth. These stress boundaries may relate to rheological discontinuities in the forearc, and may help us unravel how forearc composition influences subduction zone behaviour and seismic hazard.

Moss, Robb, Tristan Gebhart, David Frost, and Christian Ledezma. Flow-Failure Case History of the Las Palmas, Chile, Tailings Dam. Pacific Earthquake Engineering Research Center, University of California, Berkeley, CA, January 2019. http://dx.doi.org/10.55461/gvif2980.

Full text
Abstract:
This report documents the flow failure of the Las Palmas tailings dam that was induced by the 27 February 2010 Maule Chile M8.8 earthquake. The Las Palmas site is located in Central Chile in Region VII near the town of Talca. Construction of the tailings dam occurred between 1998 as part of a gold mining operation and was no longer in active use. The ground shaking from the earthquake induced liquefaction of the saturated tailings material and resulted in a flow failure that ran out upwards of 350 m, flowing downslope in two directions. This report is broken into three sections: A summary of the construction and flow failure of the Las Palmas tailings dam; Details on the field investigations at the site, including the 2010 GEER reconnaissance, 2011 litigation support [DICTUC 2012], and the recent PEER–NGL-funded 2017 investigation; and Back-analysis of the flow failure by Gebhart [2016] to estimate the residual strength. The goal of this work is to provide a “high-quality” flow-failure case history to augment the existing database. The existing database is composed of roughly thirty case histories of varying quality (e.g., Weber et al. [2015] and Kramer and Wang [2015]). Herein, the term “high-quality” means that the in situ measurements were made in a controlled and repeatable manner, and that the back-analysis of the residual strength was performed considering static and dynamic effects of the slide mass. The results from this research indicate that the median back-analyzed residual strength of the liquefied material is ~8.3 kPa (~173 psf) at a pre-earthquake vertical effective stress of 2 atm (~200 kpa or 4000 psf), which is correlated to a median SPT blow count of N1,60~2.5, a median CPT tip resistance of qc1~1.3 MPa, and a median shear-wave velocity of VS1~172 m/sec. The back analyzed residual strength has a nominal coefficient of variation of 5.5% determined using a sensitivity analysis.

The Latin American and Caribbean region is highly exposed to natural disasters. The social and economic impact of these events has been historically very significant and it is showing an increasingly growing trend.

Preliminary impact assessments indicate that the powerful January 2010 Port-au-Prince earthquake killed more than 225,000 people and caused damages and losses of about US$8 billion dollars (about 120 percent of last year GDP). This technical note presents the current Inter-American Development Bank Strategic Approach to catastrophe risk financing and discusses the technical and economic underpinnings for the proposed disaster-linked financial instruments. The paper considers the accumulated stock of knowledge about disaster risk management over the past decade and discusses how it is being deployed effectively in the region by the Bank.

Abstract:
Our knowledge of the trade effects of domestic infrastructure is very limited. The reason is twofold. First, data needed to examine these effects are not readily available. Second, identifying such effects requires properly addressing potential endogeneity problems affecting the relationship between internal infrastructure and trade. In this paper, we overcome these limitations by combining firm-level data with detailed geo-referenced information on Chile and by exploiting the earthquake that took place in this country in 2010 as an exogenous source of variation in available infrastructure and thereby in transport costs. We find that diminished transportation infrastructure had a significant negative impact on firms' exports.

Abstract:
Over the past decade, several long-duration subduction earthquakes took place in different locations around the world, e.g., Chile in 2010, Japan in 2011, China in 2008, and Indonesia in 2004. Recent research has revealed that long-duration, large-magnitude earthquakes may occur along the Cascadia subduction zone of the Pacific Northwest Coast of the U.S. The duration of an earthquake often affects the response of structures. Current seismic design specifications mostly use response spectra to identify the hazard and do not consider duration effects. Thus, a comprehensive understanding of the effect of the duration of the ground motion on structural performance and its design implications is an important issue. The goal of this study was to investigate how the duration of an earthquake affects the structural response of special concentric braced frames (SCBFs). A comprehensive experimental program and detailed analytical investigations were conducted to understand and quantify the effect of duration on collapse capacity of SCBFs, with the goal of improving seismic design provisions by incorporating these effects. The experimental program included large-scale shake table tests, and the analytical program consisted of pre-test and post-test phases. The pre-test analysis phase performed a sensitivity analysis that used OpenSees models preliminarily calibrated against previous experimental results for different configuration of SCBFs. A tornado-diagram framework was used to rank the influence of the different modeling parameters, e.g., low-cycle fatigue, on the seismic response of SCBFs under short- and long-duration ground motions. Based on the results obtained from the experimental program, these models were revisited for further calibration and validation in the post-test analysis. The experimental program included three large-scale shake-table tests of identical single-story single-bay SCBF with a chevron-brace configuration tested under different ground motions. Two specimens were tested under a set of spectrally-matched short and long-duration ground motions. The third specimen was tested under another long-duration ground motion. All tests started with a 100% scale of the selected ground motions; testing continued with an ever-increasing ground-motion scale until failure occurred, e.g., until both braces ruptured. The shake table tests showed that the duration of the earthquake may lead to premature seismic failure or lower capacities, supporting the initiative to consider duration effects as part of the seismic design provisions. Identical frames failed at different displacements demands because of the damage accumulation associated with the earthquake duration, with about 40% reduction in the displacement capacity of the two specimens tested under long-duration earthquakes versus the short-duration one. Post-test analysis focused first on calibrating an OpenSees model to capture the experimental behavior of the test specimens. The calibration started by matching the initial stiffness and overall global response. Next, the low-cycle fatigue parameters were fine-tuned to properly capture the experimental local behavior, i.e., brace buckling and rupture. The post-test analysis showed that the input for the low-cycle fatigue models currently available in the literature does not reflect the observed experimental results. New values for the fatigue parameters are suggested herein based on the results of the three shake-table tests. The calibrated model was then used to conduct incremental dynamic analysis (IDA) using 44 pairs of spectrally-matched short- and long-duration ground motions. To compare the effect of the duration of ground motion, this analysis aimed at incorporating ground-motion variability for more generalized observations and developing collapse fragility curves using different intensity measures (IMs). The difference in the median fragility was found to be 45% in the drift capacity at failure and about 10% in the spectral acceleration (Sa). Using regression analysis, the obtained drift capacity from analysis was found to be reduced by about 8% on average for every additional 10 sec in the duration of the ground motion. The last stage of this study extended the calibrated model to SCBF archetype buildings to study the effect of the duration of ground motion on full-sized structures. Two buildings were studied: a three-story and nine-story build that resembled the original SAC buildings but were modified with SCBFs as lateral support system instead of moment resisting frames. Two planer frames were adopted from the two buildings and used for the analysis. The same 44 spectrally-matched pairs previously used in post-test analysis were used to conduct nonlinear time history analysis and study the effect of duration. All the ground motions were scaled to two hazard levels for the deterministic time history analysis: 10% exceedance in 50 years and 2% exceedance in 50 years. All analysis results were interpreted in a comparative way to isolate the effect of duration, which was the main variable in the ground-motion pairs. In general, the results showed that the analyzed SCBFs experienced higher drift values under the long-duration suite of ground motions, and, in turn, a larger percentage of fractured braces under long-duration cases. The archetype SCBFs analysis provided similar conclusions on duration effects as the experimental and numerical results on the single-story single-bay frame.

Abstract:
This is the first of two volumes that constitute the Annual Report of the Inter-American Development Bank. The two-volume report contains a review of the Bank's operations in 2010 (loans, guarantees, and grants) and, in a separate volume, Management's Discussion and Analysis: Ordinary Capital, and the financial statements of the Bank. By the end of 2010, the IDB had approved $197 billion in loans and guarantees to finance projects with investments totaling over $420 billion, as well as $4.1 billion in grants and contingent-recovery technical cooperation financing. Among other tasks, in early 2010 implementation began of the new integrated system of capital adequacy and portfolio analysis, which includes elements related to financial projections and asset and liability management. Throughout the year the Bank worked diligently in its core mission, collaborating with its borrowing member countries in addressing the Region's development agenda, focusing resources and technical expertise on assisting the neediest and most vulnerable. Following the earthquakes in Haiti and Chile and other natural disasters, the Bank approved country-specific relief and reconstruction operations.
