The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline.

Earthquakes are some of the most dynamic features of the Earth. This multidisciplinary volume presents an overview of earthquake processes and properties including the physics of dynamic faulting, fault fabric and mechanics, physical and chemical properties of fault zones, dynamic rupture processes, and numerical modeling of fault zones during seismic rupture. This volume examines questions such as: • What are the dynamic processes recorded in fault gouge? • What can we learn about rupture dynamics from laboratory experiments? • How do on-fault and off-fault properties affect seismic ruptures? • How do fault zones evolve over time? Fault Zone Dynamic Processes: Evolution of Fault Properties During Seismic Rupture is a valuable resource for scientists, researchers and students from across the geosciences interested in the earthquakes processes.

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.

Faults are primary focuses of both fluid migration and deformation in the upper crust. The recognition that faults are typically heterogeneous zones of deformed material, not simple discrete fractures, has fundamental implications for the way geoscientists predict fluid migration in fault zones, as well as leading to new concepts in understanding seismic/aseismic strain accommodation. This book captures current research into understanding the complexities of fault-zone internal structure, and their control on mechanical and fluid-flow properties of the upper crust.

Faults zones are three-dimensional structures that separate distinct hanging wall and footwall lithologic units and commonly exhibit mechanical and hydrological properties distinct from protolith. As such, they exert a fundamental control on a wide variety of societally relevant geological processes, from the transport and/or trapping of ore-bearing fluids and hydrocarbons to the generation of earthquakes. Fluids commonly mediate the structural development of fault zones, particularly through physical and chemical alteration of fault rocks during diagenesis and mechanical processes such as hydrofracturing. Collectively, these processes can lead to substantial variations in fault hydromechanical properties and thereby a fault zone's response to later fault slip and fluid flow events. Very little previous research has attempted to provide a holistic examination of this interplay between faults and fluids in the crust, which requires recognizing and exploring the relationship between tectonics, fault rock mechanics, fluids, and diagenesis. This dissertation attempts to fill this gap in our knowledge by examining fluid-fault interactions in the Rio Grande rift of New Mexico. Chapter 1 describes the results of research that utilized calcite cements in fault damage zones as a geochemical record of fluid source to evaluate tectonic controls on fluid migration during the development of the Rio Grande rift. These data show that the distribution of faults, bedrock, and syntectonic sediments of varying hydrological and mechanical properties results in a predictable spatial and temporal distribution of fault-zone fluid flow pathways during basin extension. Chapter 2 evaluates the role of syntectonic calcite cementation in the development of fault-zone architecture and permeability structure in the Loma Blanca fault zone, Socorro Basin, NM. It additionally demonstrates that cementation and proximity to zones of structural complexity such as fault relays exert a profound impact on the location and magnitude of fluid flow over time within developing normal fault systems. Chapter 3 presents U-Th geochronology and stable isotope data from syntectonic calcite veins in the Loma Blanca fault zone which constrain earthquake recurrence intervals over >400 ka. These data provide a critical first test of competing earthquake frequency models for intraplate faults.

This book contains selected papers presented at the NATO Advanced Study Institute on "Strong Ground Motion Seismology", held in Ankara, Turkey between June 10 and 21, 1985. The strong ground motion resulting from a major earthquake determines the level of the seismic hazard to enable earthquake engineers to assess the structural performance and the consecutive risks to the property and life, as well as providing detailed information to seismologists about its source mechanism. From the earthquake engineering point the main problem is the specification of a design level ground motion for a given source-site-structure-economic life and risk combination through deterministic and probabilistic approaches. In seismology the strong motion data provide the high frequency information to determine the rupture process and the complexity of the source mechanism. The effects of the propagation path on the strong ground motion is a research area receiving sub stantial attenuation both from earthquake engineers and seismologists. The Institute provided a venue for the treatment of the subject matter by a series of lectures on earthquake source models and near field theories; effects of propagation paths and site conditions, numerical and empirical methods for prediction; data acquisition and analysis; hazard assessment and engineering application.

The Farmington Siding landslide complex is in Davis County, Utah, about 25 kilometers north of Salt Lake City. The landslide complex covers approximately 19.5 square kilometers and is one of 13 late Pleistocene/Holocene features along the Wasatch Front mapped by previous investigators as possible liquefaction-induced lateral spreads. The Farmington Siding landslide complex is in a largely rural area, but state and interstate highways, railroads, petroleum and natural-gas pipelines, and other lifelines cross the complex. Continued population growth along the Wasatch Front increases the likelihood of urban development within and adjacent to the landslide complex. Development along the Wasatch Front has proceeded with little consideration of hazards associated with liquefaction-induced landslides. Slope-failure mechanisms, extent of internal deformation, and timing of landslide events are poorly understood, and these factors must be evaluated to enable local governments to effectively plan for development and implement hazard-reduction strategies as needed. The purpose of this study is to assess the hazard associated with future liquefaction-induced landsliding within and adjacent to the Farmington Siding landslide complex by evaluating slope-failure modes and extent of internal deformation within the complex, inferring the geologic and hydrologic conditions under which landsliding occurred, determining the timing of landsliding, and evaluating the relative likelihood of various earthquake source zones to trigger liquefaction-induced landsliding. We chose the Farmington Siding landslide complex for this study because of the distinctiveness of geomorphic features on the northern part of the complex and the presence of landslide deposits that are clearly of different ages. Furthermore, because much of the area is rural, appropriate land-use planning measures can still be implemented to protect future development.
