This book was released on 2011-10 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: El proyecto sobre la amenaza sismica de Villavicencio se esta desarrollando desde 2006 y esta liderado por el grupo de investigacion de la Universidad del Meta de Colombia "Estudios sobre riesgo sismico y amenazas naturales del Piedemonte Llanero" con el apoyo del Grupo de Geofisica del Departamento de Geociencias de la Universidad Nacional de Colombia de Bogota D.C. La ciudad de Villavicencio tiene cerca de 500.000 habitantes. Su poblacion se ha quintuplicado en los ultimos 40 anos y su economia ha crecido de una manera casi exponencial para las dos ultimas decadas. Estos entre otros factores han producido un crecimiento desmesurado y desorganizado de la ciudad, la cual no tiene regulada de una manera adecuada el uso y la ocupacion de su suelo, lo que ha dado como consecuencia el incremento de su vulnerabilidad frente a la amenaza sismica, que es alta tal como se muestra en este libro que exhibe los diferentes resultados del proyecto."

This book was released on 2015 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the assessment of seismic risk, hazard is one of its main components, given that, from a probabilistic perspective, provides the annual rates of exceedance of the intensities of strong motion in the site or region of analysis, or alternatively, provides a set of stochastically generated events that fully represent the hazard of the site or region of analysis. This thesis provides methodological elements of two major components of the assessment of seismic hazard: the attenuation of strong motion and site effects. A numerical procedure for the calibration of a source spectrum model to find the optimal combination of seismological parameters and derive unbiased ground motion prediction equations is presented, using available accelerogram recordings as calibration target. The source spectrum model is used to compute the radiated spectra of SH-waves for different seismic moments and hypocentral distances, combining point (far field) and finite (near field) source models. The expected value of the peak ground acceleration is computed from the radiated spectra using random vibrations theory. A genetic algorithm is used to search for the source spectrum parameters that best fit the available strong motion recordings. The procedure can be applied to any region with statistically significant accelerogram records. The proposed methodology is followed to derive spectral ground motion prediction equations compatible with the seismo-tectonic environment of Colombia, using 206 strong motion recordings as the calibration target. The obtained ground motion prediction equations are compared with those used in the latest national seismic hazard assessment study of Colombia. The comparison shows that the strong ground motion prediction equations obtained using the proposed methodology have lower residual bias, showing reasonable matching between them and the real strong motion recordings. Furthermore, in this thesis a methodology for assessing site effects in cities was developed, which is based on the geometry of the prevailing geological formations and their relation to soft soil deposits. The methodology allows to calculate the soil dynamic response at any location within a city, using a geotechnical seismic response model, which is based on the generation of synthetic stratigraphies from the definition of depth profiles of geotechnical properties relevant in assessing the seismic amplification. These geotechnical properties are modeled as random variables, in order to include in the model, in a consistent way, the uncertainty associated with the lack of the exact value of these properties in depth. This site effects model can be applied with three main objectives: i) obtaining transfer functions of the response spectrum for risk assessment, ii) generating Shake-Maps for emergency response purposes, and iii) the seismic microzonation of a city and obtaining elastic seismic-resistant design spectra. The methodologies presented here are a first step towards the construction of more detailed models of seismic hazard, which adequately reflect the specific conditions of the region where they are applied. This leads to the definition of more accurate models of seismic risk, to reduce the uncertainties associated with the assessment of the hazard and, therefore, to obtain tighter estimates of losses in order to provide decision makers with reliable information for the proper management of seismic risk.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Colombia se encuentra en un complejo entorno tectónico debido a la convergencia de diferentes placas tectónicas, lo que genera zonas de subducción y rupturas corticales que han generado sismos de magnitudes considerables en el pasado. La historia reciente de Colombia se ha visto marcada por sismos como los de Popayán en 1983 y Armenia en 1999, los cuales han generado importantes pérdidas económicas además de causar cintos de víctimas mortales. Estos eventos han tenido un impacto tan importante que han servido como referencia para el desarrollo de normativas de construcción sismo resistente, para las cuales se han desarrollado estudios nacionales de amenaza sísmica con el objetivo de definir los parámetros para la construcción de espectros de diseño para edificaciones convencionales. Debido a la importancia de conocer las probabilidades de excedencia de ciertos valores de aceleración, se realiza un modelo probabilista de amenaza sísmica a partir de información actualizada referente a fallas sísmicas...

Book Synopsis Volcanic Unrest by : Joachim Gottsmann
Download or read book Volcanic Unrest written by Joachim Gottsmann and published by Springer. This book was released on 2018-12-18 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book summarizes the findings of the VUELCO project, a multi-disciplinary and cross-boundary research funded by the European Commission's 7th framework program. It comprises four broad topics: 1. The global significance of volcanic unrest 2. Geophysical and geochemical fingerprints of unrest and precursory activity 3. Magma dynamics leading to unrest phenomena 4. Bridging the gap between science and decision-making Volcanic unrest is a complex multi-hazard phenomenon. The fact that unrest may, or may not lead to an imminent eruption contributes significant uncertainty to short-term volcanic hazard and risk assessment. Although it is reasonable to assume that all eruptions are associated with precursory activity of some sort, the understanding of the causative links between subsurface processes, resulting unrest signals and imminent eruption is incomplete. When a volcano evolves from dormancy into a phase of unrest, important scientific, political and social questions need to be addressed. This book is aimed at graduate students, researchers of volcanic phenomena, professionals in volcanic hazard and risk assessment, observatory personnel, as well as emergency managers who wish to learn about the complex nature of volcanic unrest and how to utilize new findings to deal with unrest phenomena at scientific and emergency managing levels.
