Recent theoretical and technique developments, novel laboratory experiments, dense seismic arrays, and other high quality data sets offer opportunities for advancing significantly the understanding of earthquakes and faults. This volume describes the state-of-the-art in several frontiers in studies of earthquakes and faults. The subjects covered include analysis of earthquake source properties, models of dynamic ruptures and slow slip events, imaging fault zones and the crust, detection of small earthquakes, high-resolution laboratory fracturing experiments, temporal changes of seismic properties, inversions of focal mechanisms to stress and more. The volume will be useful to students and professional researchers from Earth Sciences, Material Sciences, Solid Mechanics and other disciplines, who are interested in properties and processes of earthquakes and faults.

Considerable progress has been made recently in quantifying geometrical and physicalproperties of fault surfaces and adjacent fractured and granulated damage zones inactive faulting environments. There has also been significant progress in developingrheologies and computational frameworks that can model the dynamics of fault zoneprocesses. This volume provides state-of-the-art theoretical and observational resultson the mechanics, structure and evolution of fault zones. Subjects discussed includedamage rheologies, development of instabilities, fracture and friction, dynamic ruptureexperiments, and analyses of earthquake and fault zone data.

Earthquake fault zones exhibit hierarchical damage and granular structures with evolving geometrical and material properties. Understanding how repeated brittle deformation form the structures and how the structures affect subsequent earthquakes is a rich problem involving coupling of various processes that operate over broad space and time scales. The diverse state-of-the-art papers collected here show how insight can come from many fields including statistical physics, structural geology and rock mechanics at large scales; elasticity, friction and nonlinear continuum mechanics at intermediate scales; and fracture mechanics, granular mechanics and surface physics at small scales. This volume will be useful to students and professional researchers from Earth Sciences, Material Sciences, Engineering, Physics and other disciplines, who are interested in the properties of natural fault zones and the processes that occur between and during earthquakes.

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.

Geophysicists use seismic signals to image structures in the Earth's interior, to understand the mechanics of earthquake and volcanic sources, and to estimate their associated hazards. Keiiti Aki developed pioneering quantitative methods for extracting useful information from various portions of observed seismograms and applied these methods to many problems in the above fields. This volume honors Aki's contributions with review papers and results from recent applications by his former students and scientific associates pertaining to topics spawned by his work. Discussed subjects include analytical and numerical techniques for calculating dynamic rupture and radiated seismic waves, stochastic models used in engineering seismology, earthquake and volcanic source processes, seismic tomography, properties of lithospheric structures, analysis of scattered waves, and more. The volume will be useful to students and professional geophysicists alike.

Statistical Seismology aims to bridge the gap between physics-based and statistics-based models. This volume provides a combination of reviews, methodological studies, and applications, which point to promising efforts in this field. The volume will be useful to students and professional researchers alike, who are interested in using stochastic modeling for probing the nature of earthquake phenomena, as well as an essential ingredient for earthquake forecasting.

heterogeneous structures, especially when the data quality is not very high. GAUTIER et al. perform tomographic inversion of local earthquake arrival times for crustal structure and earthquake locations in the actively rifting Gulf of Corinth. The velocities image the rift basin and the hypocenters image a regional-scale detachment fault. Inthe third group of papers, SNIEDER reviews theoretical concepts governing changes of coda waves due to small localized perturbations in the medium properties or source location, and describes how to estimatethe resulting meanand varianceofthe travel-time perturbations. CAMPILLO reviews theoretical results on properties of coda waves in asymptotic multiple-scattering regime, and how to construct Green functions from coda waves and ambient seismic noise. The results are illustrated with applications of imaging velocity structures in Alaska and California. WEGLER et al. use the theory of radiative transfer to model the transport of seismic energy in 2-D and 3-D acoustic random media. The theory accounts correctly for the direct wave front, envelope broadening caused by multiple forward scattering, and late coda caused by multiple wide-angle scattering. However, for very heterogeneous media the radiative transfer results di?er from those of the full wave equation. ZENG develops a set of scattered wave energy equations that include scattered surface waves and conversions of body waves to surface wave scattering. Numerical results show that scattered wave energy can be approximated well by body-wave scattering at earlier times and short distances, but at large distances scattered surface waves dominate the scattered body waves at surface stations.
