Geodetic And Geophysical Effects Associated With Seismic And Volcanic Hazards
Author: José Fernandez
Publisher: Springer
ISBN: 3034878974
Category : Science
Languages : en
Pages : 324
Book Description
Although geodetic monitoring techniques have been widely used in areas of seismic or volcanic activity, the difficulty inherent to their discrete nature means that they must be deployed carefully to ensure the best possible detection or sensitivity of these points (see e. g. , BALDI and UNGUENDOLI, 1987; JOHNSON and WYATT, 1994; SEGALL and MATTHEWS, 1997; Yu et al. , 2000). In many cases, a more global monitoring method, is required yet at the same time one that offers the highest level of sensitivity which enables detection of the phenomenon. Interferometry radar (InSAR) techniques have been shown to play an important role in seismic and volcanic monitoring because they cover large areas (100 x 100 km) and can be easily systematized in monitoring (see e. g. , MASSONNET and FEIGL, 1998; BDRGMANN et al. , 2000; MASSONNET and SIGMUNDSON, 2000; HANSSEN, 2001). The limitations inherent to the GPS and InSAR techniques (mainly observations at discrete surface points in the case of GPS and existence of non-coherent areas and the fact that, at present, the three displacement components cannot be obtained in SAR interferometry) can be overcome by using them together or other techniques (e. g. , PUGLISI and COLTELLI, 2001; RODRiGUEZ-VELASCO et al. , 2002; FERNANDEZ et al. , 2003).

Why INEGI? The saga of a Mexican institution in search of the truth
Author: Instituto Nacional de Estadística y Geografía
Publisher: INEGI
ISBN:
Category : Antiques & Collectibles
Languages : en
Pages : 516
Book Description
The book presents the National Institute of Statistics and Geography, what is and how it has developed over time, since it was founded in 1983. The Institute is today an eminently technical and at the same time autonomous body of the Mexican State.Beyond a chronology of events, this book raises two needs that have marked the Institute's evolution: the first, to properly measure the many components of reality, whether social, economic or natural; and the second, decisive for the public's trust and whose absence would invalidate the purposes of the previous need, to preserve the information from any consideration, other than strictly professional, in all stages of its production and dissemination.This work conveys INEGI's transcendence as an indispensable institution for the country to respond to the fundamental question, common to all human beings: to know and understand the reality of their environment.

Volcanic Unrest
Author: Joachim Gottsmann
Publisher: Springer
ISBN: 331958412X
Category : Nature
Languages : en
Pages : 313
Book Description
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.
