Abstract:
The Tirúa-Mocha Island area (38.2°-38.4° S) in southern Chile has been affected by two megaearthquakes in only 50 years: the 1960 Mw=9.5 Valdivia earthquake and 2010 Mw=8.8 Maule earthquake. We studied in the field the vertical ground movements occurred during the interseismic period between both earthquakes and the coseismic period of 2010 Maule earthquake and 2011 Mw=7.1 Araucanía earthquake. During the 1960 earthquake, vertical coseismic ground movements are typical of subduction related earthquakes with Mocha Island, located close to the trench, experienced bigger ground uplift (150 cm) than that occurred in Tirúa (-20 cm), place located in the continental margin at the latitude of Mocha Island. Then during the 1960-2010 interseismic period, the 1960 coseismic uplift remained at Mocha Island unlike the normal interseismic subsidence that occurred northward at Arauco Peninsula and Santa María Island. Also Tirúa experienced the biggest interseismic uplift (180 cm) in all the area affected later by 2010 Maule earthquake. Then during the 2010 Mw=8.8 Maule earthquake an anomalous vertical coseismic ground uplift occurred in the study area, opposite to that of 1960 since Mocha Island experienced lower (25 cm) ground uplift than Tirúa (90 cm). Subsequently, during the Araucanía 2011 earthquake a ground uplift in Mocha Island (50 cm) and subsidence at Tirúa (20 cm) occurred. These unexpected vertical ground movements can be explained by the existence of an upper plate splay fault located below the sea bottom between Tirúa and Mocha Island: the Tirúa-Mocha splay fault. Considering the last seismic cycle, the activity of this fault would have started after the 1960 Valdivia earthquake. During 2010 Maule earthquake, the main slip occurred at Tirúa Mocha splay fault. Finally during 2011 Araucanía earthquake, the slip occurred mainly at the updip of Wadati-Benioff plane with probable normal activity of Tirúa-Mocha splay fault. Simple elastic dislocation models considering the Wadati-Benioff plane and the Tirúa-Mocha splay fault activity, can account for all the vertical ground movements observed during 1960 earthquake, the 1960-2010 interseismic period, the 2010 Maule earthquake and the 2011 Araucanía earthquake.

Abstract:
This article describes the seismic performance of a group of ports in southern Chile during the 27 February 2010 Maule, Chile, earthquake. Direct costs in damage for these ports have been estimated in slightly less than US$300 million. Similarly to the performance of other ports in previous earthquakes, the most common failures observed were soil related, and include soil liquefaction, lateral spreading, and pile failures. Structural failures were mostly due to short pile effects and natural torsion. This situation is contrasted herein with the performance of the South Coronel Pier, which was seismically isolated in 2007. The isolated portion of this port remained operational after the earthquake, which was the main design goal. Post-earthquake preliminary analyses indicate that the structure was subjected to deformations and forces of approximately 60% to 70% of their design values, respectively. Piles and superstructure remained within elastic range, while the isolators experienced important nonlinear deformations.

Abstract:
The 2010 Maule earthquake is one of the largest events ever recorded with modern instruments. We used the continuous GPS (cGPS) records to invert for the kinematic rupture process using an elliptical sub-patch approximation. In agreement with previous inversions, the largest slip is found in the northern part of the rupture zone. By cross-correlating signals from cGPS and strong motion records (SM) located in the northern part of the rupture zone, we identified two distinct seismic pulses. Using the arrival time of these pulses, we propose a short-period (<20 s) rupture process, the zone where these pulses are generated is situated near 35.5°S, in agreement with the area with the highest seismic slip and maximum observed intensity. Finally, we compare the strong motion records at the same sites for the 1985 Mw 8 Valparaíso earthquake and the Maule earthquake. We found that spectral contents and duration of the records of these two events were very similar. Thus, at least in the northern part of the rupture, the Maule earthquake radiated high frequency waves like an Mw 8 earthquake.

Abstract:
Abstract To investigate the dynamic response of the outer accretionary prism updip from the patch of greatest slip during the 2010 Mw 8.8 Maule earthquake (Chile), 10 ocean-bottom seismometers (OBSs) were deployed from May 2012 to March 2013 in a small network with an inter-instrument spacing of 7–10 km. Nine were recovered, with four recording data from intermediate-band three-component seismometers and differential pressure gauges, and five recording data from absolute pressure gauges (APGs). All instruments were also equipped with fluid flow meters designed to detect very low rates of flow into or out of the seafloor. We present hypocenters for local earthquakes that have S-P times &lt;17 s (i.e., within ∼125 km of the network), with a focus on events located beneath or near the network. Most of the seismicity occurred either near the boundary between the active accretionary prism and continental basement or in the outer rise seaward of the trench. For many outer-rise earthquakes, the P and S arrivals are followed by a distinctive T-phase arrival. Very few earthquakes, and none located with hypocenters deemed “reliable,” were located within the active accretionary prism or on the underlying plate boundary. Nonvolcanic tremor-like pulses and seafloor pressure transients (but no very-low-frequency earthquakes or fluid flow) were also detected. Many of the tremor observations are likely T-phases or reverberations due to soft seafloor sediments, although at least one episode may have originated within the accretionary prism south of the network. The transient seafloor pressure changes were observed simultaneously on three APGs located over the transition from the active prism to the continental basement and show polarity changes over short distances, suggesting a shallow source. Their duration of several hours to days is shorter than most geodetic transients observed using onshore GPS networks. The results demonstrate the need for densely spaced and large-aperture OBS networks equipped with APGs for understanding subduction zone behavior.

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.

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:
The 2010, moment magnitude 8.8 earthquake that occurred near Maule, Chile caused major damages to several piers in the Port of Coronel located approximately 160 kilometers (100 miles) to the South of the earthquake epicenter. One of the piers, the North Pier, experienced significant lateral spreading that was caused from liquefaction of the soils at the approach zone of the pier. Damages from lateral spreading and liquefaction effects consisted of sheet pile welding ruptures of the cross-support beams, stiffener buckling, pile displacements, pile rotations, and pier deck displacement. Researchers analyzed the North Pier after the earthquake and documented in detail the damage caused by lateral spread displacements. This study introduces a simplified performance-based procedure called the "Simplified Modeling Procedure" that is used for the analysis of piles supporting a pier that are exposed to lateral spread displacements. The procedure uses the software LPILE, a common program for analyzing a single pile under lateral loading conditions, to evaluate a more complex multi-pile pier design. Instead of analyzing each of the piles in a given pier individually, the procedure utilizes what is known as a "Super Pile" approach to combine several piles into a single representative pile during the analysis. To ensure displacement compatibility between each "Super Pile" in the analysis, the "Super Piles" are assumed to be fully connected at the top of each "Super Pile" to the pier deck. The Simplified Modeling Procedure is developed and tested using the case study history of the North Pier from the Port of Coronel during the 2010 Maule earthquake. The Simplified Modeling Procedure incorporates p-y springs with a lateral push-over analysis. This approach allows the analysis to be performed in a matter of seconds and allows the user to more easily draw the needed correlations between the rows of piles. This procedure helps identify that different rows of piles either contribute to the movement of the pier or contribute to the bracing of the pier. The procedure ultimately predicts the anticipated pier deck deflection by determining when all the pile rows and their respective shear forces are in equilibrium. The Simplified Modeling Procedure predicted that the North Pier experienced deflections between approximately 0.31 meters (1.01 feet) and 0.38 meters (1.26 feet). The predicted deflections and rotations determined using the procedure were determined to be a relatively close representation of the observations made during the post-earthquake reconnaissance observations.

En el terremoto del Maule del 27 de Febrero del 2010 (27-F) se produjo el fenómeno de licuación de los suelos en una gran cantidad de zonas. En el presente estudio, se efectuó un extenso catastro de los sitios que presentaron este fenómeno, encontrándose más de 180 sitios distribuidos desde La Calera hasta el Lago Llanquihue, abarcando una distancia aproximada de 950 km. De este catastro fue posible constatar fallas en terrenos planos, desplazamiento lateral (lateral spreading), daños a puentes y pasos a desnivel, puertos y muelles, terraplenes de acceso, fallas de taludes, terrenos ganados al mar, tranques de relaves y flotación de estructuras enterradas. En particular, las áreas más afectadas por licuación fueron al sur de la Región Metropolitana, Retiro-Parral y Concepción-Arauco. El lago Llanquihue se ubica a más de 150 km de Valdivia, donde se encontraba el acelerógrafo más austral y que midió un PGA igual a 0.14g, con una ventana de movimiento fuerte de unos 30 s. Esto deja en evidencia que en terremotos de gran magnitud, a grandes distancias de la zona epicentral, donde se producen movimientos de baja aceleración y duración, también pueden desarrollar licuación de suelos. Se realizó una revisión de los principales sismos de la historia reciente de Chile, encontrándose evidencia que permite identificar características propias del fenómeno de licuación en los terremotos de 1646, 1906, 1960 y 1985, entre otros. De estos sitios se constató la ocurrencia de licuación reiterada en varios sectores, corroborándose que terrenos que han licuado en el pasado pueden volver a licuar. Dentro de este estudio se identificaron tres sitios de especial interés, por las características y magnitud de los daños: Nancagua, Retiro y el Puerto de Coronel. En los casos de Nancagua y Retiro, los ensayos de laboratorio indican que los materiales se caracterizan por una elevada cantidad de material fino (35 y 55%) de baja plasticidad, clasificando según la USCS como SC y ML, respectivamente. Ambos materiales poseen un comportamiento contractivo con Su/σv' = 0.39 y 0.23, respectivamente. Utilizando el método simplificado de análisis de licuación, se obtiene que en ambos sectores, para aceleraciones superiores a 0.3g, el material es potencialmente licuable, condición compatible con lo observado en el terreno. En el Puerto de Coronel la estratigrafía del terreno consiste principalmente en arenas de compacidad variable y un estrato de fango. Se realizó un retroanálisis con el software FLAC 2D reproduciéndose el nivel de deformaciones observado, del cual se obtuvo una resistencia residual normalizada para el fango igual a Su/σv' = 0.07, valor compatible con este tipo de suelos. En este caso, el análisis realizado permitió concluir una falla doble: licuación de los estratos de arena suelta y deslizamiento a través del fango.

La acumulación y relajación de esfuerzos debido a la convergencia entre la Placa oceánica de Nazca y la Placa continental Sudamericana provoca en Chile terremotos de gran magnitud que pueden generar tsunamis, causando considerables pérdidas humanas y materiales, como el ocurrido el 27 de febrero del 2010 en la región del Maule ( ). Los registros históricos de grandes terremotos indican que el evento del Maule 2010 rompió la llamada “brecha sísmica de Darwin”, una zona que acumulaba energía desde 1853. Sin embargo, estudios de mega-terremotos recientes a nivel mundial han demostrado que esta información no es suficiente para entender los procesos de ruptura de grandes terremotos, para comprenderlo es fundamental conocer las estructuras globales y locales que participan en estos procesos. Esta tesis tiene como principal objetivo conocer detalladamente la estructura sísmica y plantear una interpretación tectónica del antearco marino y geometría del contacto interplaca frente a las costas del Maule a la latitud de ~ 35°S mediante datos de sísmica de alto ángulo pertenecientes al perfil P02 adquiridos por el Instituto GEOMAR (Helmholz Centre off Ocean research Kiel, Alemania) en marzo del 2008. En este trabajo se utilizó inversión tomográfica bidimensional de tiempos de viaje de ondas sísmicas compresionales refractadas y reflejadas. Los resultados muestran las estructuras principales del antearco marino, formado durante millones de años por la depositación de sedimentos provenientes desde el continente. Sedimentos depositados cercanos a la costa forman la base sur de la cuenca Mataquito, aquellos que llegan al frente de deformación han sido acrecionados y litificados debido a la compresión asociado al proceso de subducción en el margen convergente aumentando sus velocidades sísmicas desde la fosa hacia la costa formando el prisma de acreción frontal. Sedimentos más antiguos de roca consolidada metamórfica conforman el basamento continental (Cordillera de la Costa, prisma paleo acrecionario). Separando estas estructuras existe una zona de transición de velocidades sísmicas en la cual se encuentra el “backstop” (contacto entre el prisma de acreción y el basamento continental) coincidente con el límite oeste de los hipocentros de réplicas del Maule 2010 registrados por estaciones sísmicas locales. Hacia el este, la localización espacial de estos hipocentros bajo el basamento continental sugiere que el contacto entre las placas en la zona de subducción puede presentar un abrupto cambio de ángulo. En el manto oceánico superior se obtuvieron velocidades sísmicas menores a las típicas que caracterizan estas estructuras, esta disminución puede estar asociada con la hidratación del manto debido a la infiltración del agua de mar a través de las fallas normales ubicadas en el abombamiento de la placa oceánica.

Abstract:
L’étude des séismes géants de subduction présente un intérêt de premier ordre, car ils sontsuffisamment puissants pour exciter le manteau et déclencher sa relaxation visco-élastique. Cephénomène est caractérisé par des déformations à grande échelle spatiale (plusieurs milliers dekilomètres) et temporelle (plusieurs décennies). L’étude des déformations post-sismiques en surfacepar géodésie spatiale permet de contraindre les caractéristiques géométriques et rhéologiques del’interface de subduction, ouvrant ainsi la voie à l’étude du cycle sismique dans sa globalité.Le 27 février 2010 se produit le séisme de Mw 8.8, dans la région du Maule, au large du Chili. Lasubduction de la plaque Nazca sous la plaque continentale Sud-Américaine offre, pour la premièrefois, la possibilité de mesurer de manière continue et dense les déformations post-sismiques sur plusde 1500 km. Par ailleurs, plus de 10 ans de campagnes de mesures GPS, ont permis d’imager uncouplage très hétérogène tout au long de l’interface de subduction. L’imbrication alors visible entreles déformations post-sismiques et inter-sismiques, appuyée par l’étude de la sismicité historique,met ainsi en évidence les interactions inter-segments que seuls les modèles visco-élastiques de cyclesismique permettront de mieux comprendre.Cette thèse a été centrée autour de deux axes principaux, qui conduisent vers l’objectif finaldes modèles visco-élastiques de cycle sismique. Le premier et principal objectif est l’étude desdéformations post-sismiques du Maule. J’ai ainsi traité et analysé les cinq ans de données aprèsle séisme afin d’extraire le champ de déformation post-sismique. Ces données ont alors permis decontraindre les modèles visco-élastiques, grâce à la méthode des éléments finis. Un modèle combinéd’afterslip et de relaxation visco-élastique dans l’asthénosphère et dans un chenal à faible viscositétrès profond, permet ainsi d’expliquer le champ de déformation horizontal mais aussi verticalobservé. L’amplitude et la complexité des déformations en champ proche résulte de "l’afterslip",tandis que la relaxation dans le chenal permet de reproduire le très fort soulèvement de la Cordillèredes Andes. Enfin, la relaxation dans l’asthénosphère est responsable de l’extension sur plusieursmilliers de kilomètres des déformations post-sismiques. De plus, la continuité de l’effort de terrainet le traitement des données recueillies a permis de combler l’ultime gap de données. Il a ainsiété possible de déterminer un champ de vitesse inter-sismique continu sur la quasi totalité del’interface. Finalement, même si un modèle de cycle sismique à l’échelle de la subduction Chiliennen’a pas encore pu être réalisé, le modèle de post-sismique apporte déjà de nouveaux indices sur lesinteractions entre les différents segments de l’interface Chilienne, suite au dernier séisme
The study of giant earthquakes on subduction zone represents a main interest. They are indeedsufficiently powerful to excite the mantle and trigger its viscoelastic relaxation, over a very largespatial (thousands of kilometers) and temporal (several decades) scale. Postseismic deformation,monitored by spatial geodesy, are a proxy to the geometrical and rheological characteristics of thesubduction interface, that will allow us to study the whole seismic cycle.On February 27th 2010 in the region of Maule, Chile, occurs the Mw 8.8 megathrust earthquake.Yet, the subduction of the Nazca plate beneath the continental South-American plate offers, forthe first time, the opportunity to measure continuously and densely the postseismic deformationfollowing the earthquake, over more than 1500 km. Otherwise, more than a decade of GPS repeatedmeasurements allowed to image a very heterogeneous coupling all along the Chilean interface. Thevisible imbrication between postseismic deformation and interseismic loading, supported by historicaland instrumental seismicity, highlights interactions between the segments. Viscoelastic modelsof seismic cycle appears to be the only way to understand these interactions.This PhD focused on two main axes, that will lead to the development of viscoelastic modelsof seismic cycle. The first part was dedicated to the study of postseismic deformation followingthe Maule earthquake. Therefore, we processed and analyzed very precisely GPS data in orderto extract the postseismic pattern and modeled it using the finite elements method. A combinedmodel of afterslip and viscoelastic relaxation in the asthenosphere and in a low viscosity channel,extending deep along the slab, can reproduce the complex deformation pattern, horizontaly and inverticaly. The amplitude and complexity of the near-field deformation result from aseismic slip onthe fault plane, while the great uplift of the Cordillera is reproduced by relaxation in the channel.The far field extension, up to 1600 km, entirely results from relaxation in the asthenosphere. Onthe other hand, the continuity of campaign measurements was the occasion to fill the ultimate gapof data, and thus estimate a continuous interseismic velocity field from the North of the Maulerupture zone up to North Chile. Finally, even if the final viscoelastic models of seismic cycle couldnot be processed yet, the present postseismic model already brings new insights on interactionsbetween the different segments of the Chilean interface, following the last Chilean earthquake

Abstract:
Ingeniero Civil
Los lugares más alejados que evidenciaron licuación durante el Terremoto del Maule Mw 8,8 de 2010 son la Playa Calcurrupe, en el Lago Ranco, y la localidad de Las Cascadas en el Lago Llanquihue, a 280 y 350 km de la zona de ruptura, respectivamente, superando el límite de licuación propuesto por Ambraseys (1988). Este trabajo evalúa el potencial de licuación de las zonas afectadas utilizando metodologías no invasivas de terreno, de laboratorio y numéricas. La metodología no invasiva de terreno considera el uso determinístico de la velocidad de onda de corte Vs de Andrus & Stokoe (2000), y el uso probabilístico de Kayen et al. (2013). En laboratorio, se obtienen las curvas de resistencia cíclica de muestras superficiales usando la metodología simplificada de Seed et al. (1975). La metodología numérica considera el uso del software de elementos finitos OpenSees® para estudiar el aumento de presiones de poro y los cambios en esfuerzos efectivos por la propagación de ondas de corte en una columna de suelo representativa de los sitios. Los resultados de este trabajo sugieren que la aproximación mediante Vs es capaz de predecir lo observado en terreno, aun cuando es la metodología más cuestionada para establecer el potencial de licuación; la metodología de Seed et al. (1975) sólo predice la ocurrencia de licuación para altas aceleraciones superficiales (0,18 g) lo que se explica por el comportamiento dilatante de las muestras en laboratorio; el modelamiento numérico muestra una significativa amplificación sísmica, sin evidenciar licuación, siendo el modelo constitutivo sensible a la permeabilidad y a los parámetros del modelo.

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.
