An integrated resource that describes how faults are detected, what fault models predict, and current theories of fault development. Understanding Faults: Detecting, Dating, and Modeling offers a single resource for analyzing faults for a variety of applications, from hazard detection and earthquake processes, to geophysical exploration. The book presents the latest research, including fault dating using new mineral growth, fault reactivation, and fault modeling, and helps bridge the gap between geologists and geophysicists working across fault-related disciplines. Using diagrams, formulae, and worldwide case studies to illustrate concepts, Understanding Faults provides geoscientists and industry experts in oil and gas with a valuable reference for detecting, modeling, analyzing, and dating faults. -

On 17th January 1995 an inland earthquake of 7.2 magnitude occurred under Kobe city in central Japan. More than 5,500 people lost their lives. There was immense and serious damage to buildings. Researchers and engineers were shocked and astonished by the extent of the devastation and loss of life. Ground motions, generated by the event were far greater than the seismic standard for earthquake-proof designs in Japan. Recent academic progress in the fields of geology and geophysics, which would help to reduce the severity of seismic disasters, has not been sufficiently applied to the developme

What is the important geologic information recorded in Thrust Belts and Foreland Basins (TBFB) on the evolution of orogens? How do they transcript the coupled influence of deep and surficial geological processes? Is it still worth looking for hydrocarbons in foothills areas? These and other questions are addressed in the volume edited by Lacombe, Lavé, Roure and Verges, which constitutes the Proceedings of the first meeting of the new ILP task force on ""Sedimentary Basins,"" held in December 2005 at the Institut Français du Pétrole, on behalf of the Société Géologique de France.

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.

This thesis explores fluid distribution along the Nankai-Trough megathrust fault around the Kii Peninsula of Japan, where devastating earthquakes are expected to occur in the near future. Exploring fluid distribution along subduction zones is an important issue because the fluid is considered to control the occurrence of earthquakes. One of the effective strategies to estimate fluid content is retrieving receiver functions (RFs) from seismograms, but in the case of ocean-bottom seismometers (OBSs), noisy P-wave reverberations within the seawater column make such an analysis difficult. The author therefore developed a novel technique to suppress the water reverberations, which allows obtaining the fluid distribution data along a wide depth range on the plate interface. This thesis first presents the new technique, called the water layer filter method, and demonstrates its efficiency by using both synthetic and observation data. Then, using the method, a receiver function image of the Philippine Sea Plate is constructed to reveal dehydration processes of the subducting oceanic crust around the Kii Peninsula. Finally, the author performs high-frequency receiver function inversion analysis. The results indicate the presence of a thin fluid-rich sediment layer along the megathrust fault off the Kii Peninsula that acts as a pathway of fluid. Nowadays, the number of offshore observations is increasing worldwide. In this respect, the attempt to better analyze OBS data employing the new method will become more important in future studies.

The dynamics of the earthquake rupture process are closely related to fault zone properties which the authors have intensively investigated by various observations in the field as well as by laboratory experiments. These include geological investigation of the active and fossil faults, physical and chemical features obtained by the laboratory experiments, as well as the seismological estimation from seismic waveforms. Earthquake dynamic rupture can now be modeled using numerical simulations on the basis of field and laboratory observations, which should be very useful for understanding earthq

Providing the first worldwide survey of active earthquake faults, this book focuses on those described as 'seismic time bombs' - with the potential to destroy large cities in the developing world such as Port au Prince, Kabul, Tehran and Caracas. Leading international earthquake expert, Robert Yeats, explores both the regional and plate-tectonic context of active faults, providing the background for seismic hazard evaluation in planning large-scale projects such as nuclear power plants or hydroelectric dams. He also highlights work done in more advanced seismogenic countries like Japan, the United States, New Zealand and China, providing an important basis for upgrading building standards and other laws in developing nations. The book also explores the impact of major quakes on social development through history. It will form an accessible reference for analysts and consulting firms, and a convenient overview for academics and students of geoscience, geotechnical engineering and civil engineering, and land-use planning.

Geology of the Himalayan Belt: Deformation, Metamorphism, Stratigraphy presents sophisticated metamorphic and igneous rock data across various Himalayan geographic sectors, capturing their petrography, metamorphism, structure, mineralization, and regional tectonic research. With an east-west extension of about 3000 kilometers and numerous 8000 meter peaks, the Himalayas are the most spectacular mountain ranges on earth. Since the 19th century, they have provided a testing ground of global importance for the development of geodynamic concepts, from isostasy over continental collision, to more recently, feedback mechanisms between tectonics and climate. This book collects the broad range of data that's been gathered on the Himalayas over the past 50 years, providing a comprehensive analysis and interpretation on the available data that brings the scientific community a better understanding of the geological diversity and structure of the Himalayan belt, along with new techniques that have applications in a host of global geological settings.--
