This book is the result of an elaborate project initiated by the Joint Technical Committee (JTC-1) of 1) the International Society for Soil Mechanics and Geotechnical Engineering, 2) the International Association for Engineering Geology and the Environment, 3) the International Society for Rock Mechanics, and 4) the International Geotextile Society, with the focus on natural slopes and landslides. The framework of the book sets out the steps, based on recent disaster experiences in the twenty-first century, leading to the assessment of earthquake-induced landslide hazards. It contains: 1) important cases of landslides triggered by earthquakes around the world; 2) investigation into the characteristics of ground motion site response; 3) methods to determine landslide susceptibility and triggering thresholds and their comparative study; and 4) commentary on the production of earthquake-induced landslide hazard maps. All the contents are the result of the latest research on related areas. The book is a valuable resource for researchers, designers, consultants, academicians, government officials, and all others who are involved in the mitigation of coseismic landslides. The book contributes toward the development of a new chapter in disaster prevention and mitigation of landslides induced by earthquakes.
