Available in PDF, EPUB and Kindle. Book excerpt: The San Andreas Fault (SAF) near Parkfield, CA moves by a combination of aseismic creep and micro-earthquake slip. Measurements of in situ stress orientation, stress magnitude, and heat flow are incompatible with an average shear stress on the SAF greater than approximately 20 MPa. To investigate the micro-mechanical processes responsible for the low strength and creeping behavior, gouge samples from the 3 km-deep scientific borehole near Parkfield (the San Andreas Fault Observatory at Depth, SAFOD) are sheared in a triaxial rock deformation apparatus at conditions simulating those in situ, specifically a temperature of 100°C, effective normal stress of 100 MPa, pore fluid pressure of 25 MPa, and a Na-Ca-K pore fluid chemistry. The 2 mm-thick gouge layers are sheared to 4.25 mm at shear rates of 6.0, 0.6, 0.06, and 0.006 mu m/s. The mechanical data are corrected for apparatus effects and the strength of the jacketing material that isolates the sample from the confining fluid. Experiments indicate that gouge is extremely weak with a coefficient of friction of 0.14, and displays velocity and temperature strengthening behavior. The frictional behavior is consistent with the inferred in situ stress and aseismic creep observed at SAFOD. The low frictional strength likely reflects the presence of a natural fabric characterized by microscale folia containing smectite and serpentinite.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The San Andreas Fault Zone written by William A. Szary and published by . This book was released on 2019-10-21 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Andreas Fault Zone covers almost the entire length of western California. Some sections are simple while others are more complex extending from the Gulf of California through the Salton Trough into the San Gabriel and San Bernardino Mountains, through the Carrizo Plain into Parkfield, on into the San Francisco Bay, Point Reyes, and ending in the Mendocino Triple Junction. This book attempts to characterize the geologic structure, geophysics, and stratigraphy on both sides of the fault. Chapter 1 presents an overview of the setting of the San Andreas Fault System. Chapter 2 discusses the Salton Sea Trough, the Gulf of California, and the Imperial Valley. Chapter 3 presents the fault zone through the Transverse Ranges, mainly consisting of the San Gabriel and the San Bernardino Mountains. Chapter 4 addresses the creeping segment of the Carrizo Plain, Cholame, and Parkfield. Chapter 5 focuses on the San Andreas-Calaveras Fault junction along the San Benito segment. Chapter 6 discusses the South San Francisco Bay area, mainly in Santa Clara County before addressing the San Francisco Bay in Chapter 7. Chapter 8 focuses on the Point Reyes Peninsula, providing some details on the stratigraphy and structure on the peninsula. Chapter 9 closes out with a seismic review of the Mendocino Triple Junction and its interactions with the Pacific, Gorda, and North American plates.

Download or read book The Mechanics of Earthquakes and Faulting written by Christopher H. Scholz and published by Cambridge University Press. This book was released on 2019-01-03 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2001 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many faults appears to form persistent zones of weakness that fundamentally influence the distribution, arichitecture and movement patterns of crustal-scale deformation and associated processes in both continental and oceanic regions. They act as conduits for the focused migration of economically important fluids and also constitute one of the most important global geological hazards. This book brings together papers by an international group of Earth Scientists to discuss a broad range of topics centred upon the controls of fault weakening and the role of such faults during lithosphere deformation.
