Source Mechanisms of Earthquakes: Theory and Practice

by Agustín Udías, Raúl Madariaga, Elisa Buforn

Overview

This book presents an innovative new approach to studying source mechanisms of earthquakes, combining theory and observation in a unified methodology, with a key focus on the mechanics governing fault failures. It explains source mechanisms by building from fundamental concepts such as the equations of elasticity theory to more advanced problems including dislocation theory, kinematic models and fracture dynamics. The theory is presented first in student-friendly form using consistent notation throughout, and with full, detailed mathematical derivations that enable students to follow each step. Later chapters explain the widely-used practical modelling methods for source mechanism determination, linking clearly to the theoretical foundations, and highlighting the processing of digital seismological data. Providing a unique balance between application techniques and theory, this is an ideal guide for graduate students and researchers in seismology, tectonophysics, geodynamics and geomechanics, and a valuable practical resource for professionals working in seismic hazard assessment and seismic engineering.

Professor Udías has served as Editor-in-Chief of Física de la Tierra and the Journal of Seismology, and earlier as the Vice-President of the European Seismological Commission. He is a member of the Accademia Europeae, the Seismological Society of America, the American Geophysical Union, amongst other societies, and is a Fellow of the Royal Astronomical Society.

Raúl Madariaga is Emeritus Professor of Geophysics at the École Normale Supérieure (ENS) in Paris. During his career he has served as Director of the Seismological Laboratory of the Institut de Physique du Globe (IPG), and Director of the Geology Laboratory of ENS. Professor Madariaga is a Fellow of the American Geophysical Union and has been awarded the Stefan Muller medal of the European Geophysical Society and also the H. F. Reid Medal, the highest award of the Seismological Society of America. He has been an editor of several journals a well as a member of the Board of Science, and he is the author of 140 papers in leading scientific journals as well as several articles in Earth Science encyclopaedias.

Elisa Buforn is a Professor of Geophysics at the Universidad Complutense, Madrid, teaching courses on geophysics, seismology, physics and numerical methods. She has published papers on topics ranging from source fracture processes and seismicity to the seismotectonics of the Ibero-Maghrebian region and Azores-Gibraltar, and is the author of various textbooks including Solved Problems in Geophysics (Cambridge University Press, 2012). Professor Buforn currently serves as Editor-in-Chief of Física de la Tierra, and is on the editorial board of the Journal of Seismology. She has participated on many international scientific committees and is a member of the Seismological Society of America, American Geophysical Union, Royal Astronomical Society, and other distinguished societies.

Editorial Reviews

"An excellent and timely book - the first textbook to provide such a detailed and complete overview on the theory of earthquake source mechanisms, and to combine the classical continuum mechanics approach with concepts of kinematic and dynamic rupture models. This book will become an essential reference and valuable resource for researchers, professionals and graduate students."
Professor Dr Torsten Dahm, Helmholtz Centre Potsdam, GFZ German Research Centre for Geosciences

"This is an up-to-date, comprehensive, quantitative treatment of an important topic in seismology. It is unique in that theory and data analysis are both discussed in-depth, and it covers fundamental ideas from the 1960s to the very latest developments, making it the essential text for graduate students and researchers. Along with its very complete bibliography, it will become the Bible of the subject."
Professor Shamita Das, University of Oxford
