Landslides in Central California: San Francisco and Central California, July 20 - 29 1989

About The Product Published by the American Geophysical Union as part of the Field Trip Guidebooks Series . This guidebook describes an integrated program of field trips and workshops on landslides in central California. The program emphasizes state-of-the-art techniques for recognizing, mapping, analyzing, and mitigating a variety of landslide processes in urban, rural, and natural settings throughout the varied geologic terrain of central California. The workshops also draw upon pertinent examples of landslide processes from other areas to illustrate particular theories and practices. The field trips visit landslide areas and field research stations, and are interspersed with workshops on landslides induced by precipitation and earthquakes, automated terrain mapping, submarine landslide processes, field experimentation, landslide mapping techniques, landslide hazard mitigation through structural and nonstructural measures, and landslide policy issues. The three-day field trip across California from the Pacific Ocean to the Sierra Nevada focuses on the spectacular beauty and fascinating geology of the California Coast Ranges, Yosemite National Park, and Mammoth Lakes area.
