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 Sea Trough into the San Gabriel and San Bernardino Mountains, through the Carrizo Plain into Parkfield, on into the South San Francisco Bay, Point Reyes, and ending in the Mendocino Triple Junction. The 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 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.
