This essential reference for graduate students and researchers provides a unified treatment of earthquakes and faulting as two aspects of brittle tectonics at different timescales. The intimate connection between the two is manifested in their scaling laws and populations, which evolve from fracture growth and interactions between fractures. The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws - producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events. The third edition of this classic treatise presents a wealth of new topics and new observations. These include slow earthquake phenomena; friction of phyllosilicates, and at high sliding velocities; fault structures; relative roles of strong and seismogenic versus weak and creeping faults; dynamic triggering of earthquakes; oceanic earthquakes; megathrust earthquakes in subduction zones; deep earthquakes; and new observations of earthquake precursory phenomena.

Our understanding of earthquakes and faulting processes has developed significantly since publication of the successful first edition of this book in 1990. This revised edition, first published in 2002, was therefore thoroughly up-dated whilst maintaining and developing the two major themes of the first edition. The first of these themes is the connection between fault and earthquake mechanics, including fault scaling laws, the nature of fault populations, and how these result from the processes of fault growth and interaction. The second major theme is the central role of the rate-state friction laws in earthquake mechanics, which provide a unifying framework within which a wide range of faulting phenomena can be interpreted. With the inclusion of two chapters explaining brittle fracture and rock friction from first principles, this book is written at a level which will appeal to graduate students and research scientists in the fields of seismology, physics, geology, geodesy and rock mechanics.

The Mechanics of Earthquakes and Faulting presents an interdisciplinary view of earthquakes and faulting in which the main observations from seismology, geology, and geodesy are reviewed and interpreted in terms of rock mechanics principles. The book introduces the mechanics of brittle fracture and rock friction, and presents observations of natural phenomena. It goes on to investigate the nature of the tectonic loading system, explore the role of earthquakes in a wide variety of tectonic settings, and review research in the important topics of earthquake prediction and hazards research. The author's aim is to develop an overall understanding and appreciation of the mechanics of faulting processes rather than on rehearsing the methods used to study the subject. Mathematical methods are kept simple and descriptive aspects of the subject are emphasized. Each topic is illustrated with the key observational data taken from many diverse tectonic settings. A comprehensive bibliography of over 1,200 items is included for those interested in pursuing topics to a greater depth. The Mechanics of Earthquakes and Faulting is suitable as a textbook for beginning graduate students in seismology, earthquake engineering, structural geology and rock mechanics courses. It should also prove to be a valuable reference work for researchers in these areas.

Subduction zones, one of the three types of plate boundaries, return Earth's surface to its deep interior. Because subduction zones are gently inclined at shallow depths and depress Earth's temperature gradient, they have the largest seismogenic area of any plate boundary. Consequently, subduction zones generate Earth's largest earthquakes and most destructive tsunamis. As tragically demonstrated by the Sumatra earthquake and tsunami of December 2004, these events often impact densely populated coastal areas and cause large numbers of fatalities. While scientists have a general understanding of the seismogenic zone, many critical details remain obscure. This volume attempts to answer such fundamental concerns as why some interplate subduction earthquakes are relatively modest in rupture length (greater than 100 km) while others, such as the great (M greater than 9) 1960 Chile, 1964 Alaska, and 2004 Sumatra events, rupture along 1000 km or more. Contributors also address why certain subduction zones are fully locked, accumulating elastic strain at essentially the full plate convergence rate, while others appear to be only partially coupled or even freely slipping; whether these locking patterns persist through the seismic cycle; and what is the role of sediments and fluids on the incoming plate. Nineteen papers written by experts in a variety of fields review the most current lab, field, and theoretical research on the origins and mechanics of subduction zone earthquakes and suggest further areas of exploration. They consider the composition of incoming plates, laboratory studies concerning sediment evolution during subduction and fault frictional properties, seismic and geodetic studies, and regional scale deformation. The forces behind subduction zone earthquakes are of increasing environmental and societal importance.

This topical volume on the physics of megathrust earthquakes investigates many aspects of the earthquake phenomenon, from the geodynamic setting of subduction zones, to interseismic and postseismic deformation, slow-slip events, dynamic rupture, and tsunami generation. The dynamics of the seismic cycle at megathrusts is rich in various types of earthquakes, many of which only recently discovered. Our early understanding of the earthquake phenomenon was a type of stick-slip motion, where the fault is loaded by tectonic forces for an extended period, followed by rapid failure. Extensive seismic and geodetic monitoring of subduction zones has revealed a much more varied seismic behavior, where episodic fault slip can occur at any slip velocity between the background loading rate, of the order of a few atoms per second, and the fast seismic range, about a meter per second. Events that fill the gap between slow creep and fast ruptures include a host of slow earthquakes. Subduction zones therefore provide a natural laboratory to better understand the physics of earthquakes and faulting. Previously published in Pure and Applied Geophysics, Volume 176, Issue 9, 2019 The chapters “Interseismic Coupling and Slow Slip Events on the Cascadia Megathrust”, “Effect of Slip-Weakening Distance on Seismic–Aseismic Slip Patterns”, “Physics-Based Scenario of Earthquake Cycles on the Ventura Thrust System, California: The Effect of Variable Friction and Fault Geometry”, and “A Secondary Zone of Uplift Due to Megathrust Earthquakes” are available as open access articles under a CC BY 4.0 license at link.springer.com

The mechanics of earthquake faulting is a multi-disciplinary scientific approach combining laboratory inferences and mathematical models with the analysis of recorded data from earthquakes, and is essential to the understanding of these potentially destructive events. The modern field of study can be said to have begun with the seminal papers by B. V. Kostrov in 1964 and 1966. This book presents lectures delivered at the summer school ‘The Mechanics of Earthquake Faulting’, held under the umbrella of the Enrico Fermi International School of Physics in Varenna, Italy, from 2 to 7 July 2018. The school was attended by speakers and participants from many countries. One of the most important goals of the school was to present the state-of-the-art of the physics of earthquakes, and the 10 lectures included here cover the most challenging aspects of the mechanics of faulting. The topics covered during the school give a very clear picture of the current state of the art of the physics of earthquake ruptures and also highlight the open issues and questions that are still under debate, and the book will be of interest to all those working in the field.
