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.

Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.

In seismology an earthquake source is described in terms of a fault with a particular rupture size. The faulting process of large earthquakes has been investigated in the last two decades through analyses of long-period seismo grams produced by advanced digital seismometry. By long-period far-field approximation, the earthquake source has been represented by physical parameters such as s~ismic moment, fault dimension and earthquake mag nitude. Meanwhile, destruction often results from strong ground motion due to large earthquakes at short distances. Since periods of strong ground motion are far shorter than those of seismic waves at teleseismic distances, the theory of long-period source process of earthquakes cannot be applied directly to strong ground motion at short distances. The excitation and propagation of high-frequency seismic waves are of special interest in recent earthquake seismology. In particular, the descrip tion and simulation of strong ground motion are very important not only for problems directly relevant to earthquake engineering, but also to the frac ture mechanics of earthquake faulting. Understanding of earthquake sources has been developed by investigating the complexity of faulting processes for the case of large earthquakes. Laboratory results on rock failures have also advanced the understanding of faulting mechanisms. Various attempts have been made to simulate, theoretically and empirically, the propagation of short-period seismic waves in the heterogeneous real earth.

Geologists have long grappled with understanding the mechanical origins of rock deformation. Stress regimes control the nucleation, growth and reactivation of faults and fractures; induce seismic activity; affect the transport of magma; and modulate structural permeability, thereby influencing the redistribution of hydrothermal and hydrocarbon fluids. Experimentalists endeavour to recreate deformation structures observed in nature under controlled stress conditions. Earth scientists studying earthquakes will attempt to monitor or deduce stress changes in the Earth as it actively deforms. All are building upon the pioneering research and concepts of Ernest Masson Anderson, dating back to the start of the twentieth century. This volume celebrates Anderson's legacy, with 14 original research papers that examine faulting and seismic hazard; structural inheritance; the role of local and regional stress fields; low angle faults and the role of pore fluids; supplemented by reviews of Andersonian approaches and a reprint of his classic paper of 1905--

This book provides an introduction into the mechanics of faulting in the brittle crust of the Earth. It developed from my annual two-semester course on tectono mechanics for graduate students of engineering geology and of rock engineering at the Technical University of Graz (Austria). In this course, it is not my task to present a broad exposition and geometrical description of geological structures, but rather to focus on the mechanical processes that produce the structures. Although this was also the aim of my former book "Mechanics of Tectonic Faulting - Models and Basic Concepts" (1988, Elsevier), henceforth referred to as MTF, the present book is different in organisation and content, in order to meet the requirements of the courses and to include more recent developments. Instead of following the traditional subdivision into extensional, compressional and strike-slip faulting, the presentation focuses on mechanical aspects of tectonic faulting that are common to various, or even all types of tectonic faults in the brittle regime. In this way, geometrically disparate or dissimilar fault structures may be revealed as closely related by the underlying mechanical process, and complex structures may be better understood. It may be useful to indicate how the chapters in the book are organised. The first three chapters are an introduction to rock mechanics, tailored to applications in geology. It also presents the extremely useful graphical method of Mohr's stress circle, which is freely used throughout the book to keep the mathematics to an absolute minimum.

This Volume brings together twelve contributions to a symposium held in hon our of GEORG MANDL at the University of Graz, Austria on December 1-2, 1995, in the year of his 70th anniversary. It is a tribute to a formidable scientist colleague and friend and a gift of gratitude to an inspiring leader and great in stigator. A man, who began as a theoretical physicist, made fundamental contri butions to the theory of transport processes in porous media and the mechanics of granular materials, but in his forties turned to structural geology and the me chanics of tectonic faulting - a subject that has since remained at the center of his interests and the understanding of which was substantially advanced by Georg Mandl's work. In addressing different aspects of tectonic faulting, mostly if not entirely from a theoretician's or modeler's point of view, the contribu tions to this Volume reveal some of the astonishing richness of the subject, the corresponding diversity in approaches and also challenges that lie ahead. They aptly evoke the broad scientific culture brought by Georg Mandl to the study of his favourite subject, a culture he had acquired in the course of a career in a nowadays rare environment of industrial research and which interested readers will find sketched in the Biographical Note included in this Volume. As such, as well as in their own right, the papers contributed to this Festschrift should be of interest to a wider community of Earth scientists.

Earthquakes and Coseismic Surface Faulting on the Iranian Plateau is a comprehensive and well-illustrated multi-disciplinary research work that analyzes the human and physical aspects of the active faults and large-magnitude earthquakes since ancient times on the Iranian Plateau. The long-term historical, archaeological, and sociological record of earthquakes discussed here gives insight into earthquake magnitudes, recurrences, fault segmentation, clustering, and patterns of coseismic ruptures from prehistoric times to the present. The first part of the book examines oral traditions and literature of the region concerned with earthquakes, particularly in folklore, epic literature, and theology. The second part assesses dynamic phenomena associated with earthquakes, including active tectonics, archaeoseismicity, and coseismic surface faulting throughout the twentieth century. This work is a valuable technical survey and an essential reference for understanding seismic hazard analysis and earthquake risk minimization in earthquake-prone developing and developed countries throughout the world. - Provides a reference for seismic hazard evaluation and analysis - Covers data dealing with crustal deformations caused by earthquake faulting and folding since historic times - Presents unique and complete data for use in empirical relation analyses in all regions
