The book covers multi-disciplinary topics in observational, computational and applied geophysics in aspects of solid earth system. The authors provide an up-to-date overview for methods and techniques in seismology, with a focus on fault structure, strong ground motion and earthquake forecast based on full-3D earth structure models. Abundant of case studies make it a practical reference for researchers in seismology and applied geophysics.

This work presents current approaches in geophysical research of earthquakes. A global authorship from top institutions presents case studies to model, measure, and monitor earthquakes. Among others a full-3D waveform tomography method is introduced, as well as propagator methods for modeling and imaging. In particular the earthquake prediction method makes this book a must-read for researchers in the field.

This book introduces an integrated conceptual framework of the China Seismic Experimental Site (CSES), describes its scientific challenges and research priorities, and reports preliminary results coming out of observational infrastructure in seismology, tectonophysics, geodesy, geophysics and geochemistry. Preliminary community fault model, community velocity model, and community strain rate model in the CSES are described in this book. A multidisciplinary test observation system includes GNSS, seismic array, and deep drilling system under construct around middle segment of the Xiansuihe-Xiaojiang fault and other seismogenic faults in the CSES which are also introduced. This book introduces multidisciplinary topics and a wide spectrum of solid earth system to describe various disciplines, methods, and techniques through the CSES. This book presents a vision of the CSES that is dedicated to deepen the scientific understanding of continental earthquake preparation and occurrence and enhance the disaster resilience of the society. It aims at establishing a field laboratory of earthquake science, in which international and interdisciplinary cooperation could be fostered and supported. Contents of this book include the following: • History of Seismic Experiment Sites in the World. • Launching of CSES Project: Seismicity, Existed Earthquake Monitoring Networks, and Historical Seismic Disasters. • Seismotectonics and Geodynamics of the Eastern Margin of the Tibetan Plateau with Implication for the CSES. • Theoretical Framework of CSES in View of Natural Science and in view of Social Science. • Updated Earthquake Monitoring Network in China. • CSES Community Models of Geology, Structure, and Deformation. • Earthquake Forecasting Models. • CSES Products: Massive Data Procession and Distribution. • A Review of the Field Expedition of the June 17, 2019, Changning, Sichuan, M6.0 Earthquake. • Rupture Structure and Earthquake Risk of the South Longmenshan Fault Viewed by Guided Waves. • Seismic Risk Assessment. • Model of a Seismic Experimental Site with Application to the Comparative Study between CSES and ASES.

Considerable progress has been made recently in quantifying geometrical and physical properties of fault surfaces and adjacent fractured and granulated damage zones in active faulting environments. There has also been significant progress in developing rheologies and computational frameworks that can model the dynamics of fault zone processes. This volume provides state-of-the-art theoretical and observational results on the mechanics, structure and evolution of fault zones. Subjects discussed include damage rheologies, development of instabilities, fracture and friction, dynamic rupture experiments, and analyses of earthquake and fault zone data.

Recent theoretical developments, acquisitions of large seismic and other data sets, detailed geological studies and novel laboratory experiments offer new opportunities for advancing the understanding of fault zone and earthquake processes. The present and a previous volume provide broad state-of-the-art perspectives on earthquakes and crustal fault zones. Subjects discussed in this volume include imaging of fault zones and the crust, microstructural analyses of fault zone rocks, long paleoseismic record, inferences on stress, stress drops and fault geometries, properties of dynamic ruptures, generation and healing of rock damage, temporal changes of attenuation, postseismic deformation and scaling of earthquake source properties. The volume will be useful to students and professional researchers from Earth Sciences, Material Sciences, Physics and other disciplines, who are interested in properties and processes of earthquakes and faults.
