This thesis adopts the relative back-projection method to dramatically reduce “swimming” artifacts by identifying the rupture fronts in the time window of a reference station; this led to a faster and more accurate image of the rupture processes of earthquakes. Mitigating the damage caused by earthquakes is one of the primary goals of seismology, and includes saving more people’s lives by devising seismological approaches to rapidly analyze an earthquake’s rupture process. The back-projection method described in this thesis can make that a reality.

This book collects a series of review articles summarizing the outcomes of collaborative research projects on the 1999 Chi-Chi earthquake and the 2008 Wenchuan earthquake, two of the largest and most disastrous earthquakes in Asia in the last two decades. The articles cover a broad range of aspects,including these earthquakes’ fundamental mechanisms, kinematics, and the geological and geophysical background of their fracture faults. Presenting comprehensive coverage, the book offers a valuable reference guide to these two devastating earthquakes.

This volume presents a collection of contributions that were published in "Pure and Applied Geophysics - pageoph" and which deals with the major earthquake that hit Illapel, Chile on September 16, 2015 with magnitude 8.3, and associated trans-oceanic tsunami. The subducting Nazca plate beneath the Andes caused this major earthquake, generating strong shaking, permanent deformation, free oscillations of the Earth, and tsunamis. This event occurred in the flat-angle subducting segment of the plate.The generated tsunami spread throughout the entire Pacific Ocean and was recorded by numerous coastal tide gauges and open-ocean DART stations. All articles give an up-to-date account of research in one of the most active seismic zones worldwide. An introductory article by Kenji Satake rounds this collection off.

Treatise on Geophysics, Second Edition, is a comprehensive and in-depth study of the physics of the Earth beyond what any geophysics text has provided previously. Thoroughly revised and updated, it provides fundamental and state-of-the-art discussion of all aspects of geophysics. A highlight of the second edition is a new volume on Near Surface Geophysics that discusses the role of geophysics in the exploitation and conservation of natural resources and the assessment of degradation of natural systems by pollution. Additional features include new material in the Planets and Moon, Mantle Dynamics, Core Dynamics, Crustal and Lithosphere Dynamics, Evolution of the Earth, and Geodesy volumes. New material is also presented on the uses of Earth gravity measurements. This title is essential for professionals, researchers, professors, and advanced undergraduate and graduate students in the fields of Geophysics and Earth system science. Comprehensive and detailed coverage of all aspects of geophysics Fundamental and state-of-the-art discussions of all research topics Integration of topics into a coherent whole
