Full textThe main goal of this PhD dissertation is the study of the marine bivalve generic palaeodiversity throughout the Induan (Lower Triassic) - Sinemurian (Lower Jurassic) [In - Sin] interval, which includes two recovery processes, namely those of the Permo-Triassic (P/T) and Triassic - Jurassic (T/J) extinctions. A database was prepared from papers with graphic and/or descriptive information of taxa, excluding genera which were neither present nor valid throughout the interval. In addition, stratigraphic ranges (with comparison Treatise on Invertebrate Palaeontology and Compendium of Fossil Marine Animal Genera) and paleobiogeographic distributions as well as mode of life (guilds, mobile or attached, and position referred to the water column and substrate), and shell mineralogy have been re-examined.Taphonomic biases have been assessed by means of an analysis of contingency tables with adjusted residuals for different databases. In spite of having considered several biasing factors (mode of life, eurytopy or stenotopy, and so on) influencing preservation of bivalves throughout the [In - Sin], we have only recognised the strong influence of mineralogy associated to rarefaction, as it occurs during the Fanerozoic. Through the filtered data, estimates of origination, extinction and growth rates, and perform cohort analysis have been obtained. Differences in rates produce fluctuations of taxonomic diversity throughout [In - Sin]. Cohort analysis evidences detailed extinction patterns of genera arisen in each stage or the epifaunal in contrast with the infaunal genera. Finally, changes in the bivalve ecospace are studied during the [In - Sin] interval, with special emphasis on the impact of the T/J extinction.The main conclusions are 1) ecological tiering shows a very low development during the Lower Triassic as a consequence of the P/T extinction, but it is recovered during the Middle Triassic; after the T/J extinction, bivalve tiering has been scarcely affected. 2) infaunal genera became more and more abundant; this trend began since the Upper Triassic and went on the Lower Jurassic. 3) 42% of genera become extinct during the T/J extinction; impoverishment was due to a high extinction rate jointly to low origination rate; however, the diversity of guilds was not altered; this suggests that taxonomic extinction was decoupled from ecological dynamics.

Full textThis thesis studies the interaction between tectonics and the river network and how this interaction controls the patters and rates of sedimentation. This work is composed of two parts, the first one presents the results of the experimental modeling (Chapter 1 and Chapter 2), and the second one shows the study of a natural Source-To-Sink system located in Irian Jaya (Indonesia), composed by the Central Range and Cendrawasih Basin (Chapter 3). In Chapter 1 I investigate experimentally the interactions between tectonics and the drainage network and its control on along-strike sediment fluxes in wedges submitted to shortening and rainfall. We first show that the behavior (geometries and kinematics) of experimental channels evolving under uplifting conditions are similar to what is observed in natural landscapes. We show substantial differences in both the drainage organization and along-strike variations in sediment accumulations by varying the ratio of rainfall rate over shortening rate. If this ratio is high, transverse channels draining a wedge are not diverted and a line-source dispersal system develops in front of the active structure. At low ratio, the merger of drainage basins in the backlimb of frontal structures results in gridiron drainage patterns and in point-sourced depositional systems separated by areas fed only by small channels developed in the external limbs. We show that this behavior is controlled by a non-linear relation between the channel discharge and the uplift rate. In Chapter 2 experiments show that a longitudinal-dominated drainage network can be reorganized to a transverse-dominated drainage network by divide migration and captures. This reorganization of the drainage network implies variations in the size of drainage basins, and consequently, in the rates of sedimentation at the external parts of the models. The rates of sedimentation appear to be controlled not only by Tectonics and Climate, but also by the intrinsic dynamics of the geomorphic system. In addition, the drainage-network reorganization also modifies the spatial distribution of clastic bodies from point-sourced depositional systems to line-source dispersal systems. In Chapter 3 the Source-To-Sink system, made of the Central Range and the Cendrawasih basin, is analyzed. The geomorphic study the Central Range suggests that the drainage network is reorganizing following the same pattern as in the experimental modeling. A balance between the eroded volumes in the main drainage basins of the Central Range and the deposited volumes stored in the Cendrawasih basin allowed to estimate the infilling composition and it shows the basin has been mainly fed by graphitic black phyllites. The volume balance has been done using erosion rates extracted from the literature and the seismic lines of the Cendrawasih basin. This study shows that the Source-To-Sink system of the Central Range-Cendrawasih basin is a dynamic system that is in a transient state, probably since the beginning of the Central Range building in Late Miocene.

Full textRisk is understood in terms of potentially dangerous events and the vulnerability of exposed social elements. This type of analysis is linked into decision-making processes, and the difficulties associated with the implementation of risk reduction public policies are made explicit. Inherent uncertainty and reductionist approaches help explain this problem. Moreover, factors such as risk perception of decision-makers; legal contexts that impede preventive actions, and the general problem of levels of risk tolerance and acceptability also come into play.
The traditional approach to evaluating urban seismic risk is revised. This involves a consideration of the physical effects and damage to be expected in exposed elements under determined seismic conditions. Modern techniques for seismic vulnerability estimates and knowledge in the area of loss and damage are summarized. And, the better approach to physical urban seismic risk evaluation from the perspective of the author is provided.
A coherent and consistent conceptual risk model is provided based on complex non-lineal dynamic systems theory. This allows an explanation of the concept of crisis, instability and adaptability relating this to the concepts of disaster, vulnerability, risk and prevention. Urban centres are seen as complex dynamic systems. Two holistic urban seismic risk-modeling techniques are then proposed. The first methodology is based on relative indicators using hierarchical and pairwise analytical processes. The second methodology employs neural networks and fuzzy sets approaches. The two methodologies take into account the physical, economic, social and institutional variables, which allow a multidisciplinary approach to seismic risk assessment. The methods are subsequently employed in the estimation of seismic risk in the city of Bogotá, Colombia.
Finally, a risk management strategy is proposed as a planning tool, and a global proposal is made for facing collective risk, which is a clearly significant contemporary technical and social problem. Recommendations are made, as regards needed future studies and research.

Full textThis dissertation proposes a methodology for seismic damage assessment based on the capacity spectrum method but with a probabilistic approach which is supported on Monte Carlo simulation. The seismic action, the structure and the expected damage are considered and analyzed as random variables. The method, which is validated through incremental dynamic analysis, is a new, robust and powerful tool for risk analysis that can be applied to individual buildings, but also at urban and regional scales. In fact, the validation through dynamic analyses has involved creating also a probabilistic method for damage assessment, based on incremental dynamic analysis. The expected damage can be obtained for any confidence interval thus allowing the civil protection managers choosing the levels of priority or interest. As incremental dynamic analyses require accelerograms, the use of earthquake records has been preferred and it has been developed a specific technique that, for a given database, minimizes the dispersion and optimizes the number of accelerograms compatible with a given response spectrum; in this way, the uncertainties in the seismic action are considered in an appropriate manner. Although for methodological purposes it was estimated sufficient and adequate to consider only the strength properties of concrete and steel as Gaussian random variables, yet a new and interesting way to incorporate the spatial variability of the strength of beams and columns has been also proposed. The methodological developments are illustrated with numerous case studies of existing and well documented buildings. Specifically, reinforced concrete buildings with waffle slabs, classified as low-rise, mid-rise and high-rise, have been studied. This study has been conducted considering seismic actions compatible with the response spectra foreseen in the Eurocode EC8 for type 1 and type 2 earthquakes and soil classes A, B, C, D and E. The application of the method to irregular buildings confirmed the insufficiency of 2D models for asymmetric structures. Thus, the probabilistic method has been applied to two buildings of special importance for seismic scenarios of interest. The first one is the hospital of Vielha considering the seismic action with a return period of 475 years; the second one is a building located in the neighborhood of San Fernando in Lorca, which was severely damaged by the earthquake of May 2011. In this second case the seismic action has been defined deterministically by means of the two horizontal accelerograms recorded in the city. In 3D analyses the directionality effect is considered, concluding that buildings of the same type located in the same place can suffer significantly different damages depending only of their azimuthal angle. The results obtained in the case of Lorca are compatible with the observed damage. This fact supports the validity of the probabilistic method as well as that of the developments implemented in this thesis.

Full textThis work presents observational evidence clearly indicating that the energy cascade in the Alboran Sea thermocline follows the instability route. In particular we show that the internal wave breaking is due to the development of shear instabilities, and in particular Kelvin-Helmholtz (K-H) like ones. These innovative results are based on the spectral analysis of the acoustic reflectors vertical displacement recorded for the first time with a high resolution multichannel seismic system (HR-MCS), which provides a full spectral coverage between 103 m and 10 m in horizontal direction, and 2 m in vertical direction. Our analysis is based on HR-MCS data recorded in the IMPULS-2006 geological survey. The vertical displacement energy spectra of reflectors were calculated following a similar approach to that of previous studies using lower resolution seismic data. A key point to compare the spectral slopes with theoretical energy estimations is that the acoustic reflectors undulations reproduce the isopycnals vertical displacement. This is a reasonable assumption in our study area, since the Alboran Sea not subject to salinity-temperature compensating intrusions. At mesoscale level, the energy spectra of the reflectors undulation follows the Garret-Munk (1979) model, which predicts a power law spectral density with value -2. The calculated spectra show this slope value at scales larger than circa 100 m, near to the buoyancy scale calculated from oceanographic measurements (l(nh) aprox. Equal to 93m). Thus, we deduce that this spectral range corresponds to the internal waves regime in the mesoscale range. According to theory and high resolution numerical simulations, the transitional sub-range is associated in general to shear instabilities, and particularly to K-H instabilities that should display steeper spectral slopes between -2.5 and -3.0. This spectral slope range agrees with the slope calculated at the intermediate scale range (100 - 35 m), where the mean value is -2.8. A feature of the K-H structures is the laminar vortex shape, with a horizontal scale an order higher than vertical (used to be a ratio of 7/1) which also agrees with the seismic observations. Finally the Batchelor model, which is the most accepted model to describe the inertial sub-range at the smallest scales, predicts a spectral slope of -5/3. Our spectral analysis show slopes at this value (-1.64), from wavelengths smaller than circa 35 m, which suggest that the laminar vortex have collapsed and the dynamics starts to be dominated by turbulent processes. The mixing parameters obtained from HR-MCS data, can contribute to the improvement of the oceanic dynamic modelling, thanks to their high level of sinopticity, high lateral resolution and wide range of scales, covering from mesoscale to finestructure.
