This book presents current progress in landslide science and consists of four parts: (1) Progress in Landslide Science, (2) Landslide Dynamics, (3) Landslide Monitoring, and (4) Landslide Risk Assessment. It provides useful information to academics, practitioners, and government officers working on landslide risk-mitigation planning. This book can be also used as an introductory textbook for college students who wish to learn fundamental scientific achievements in the field of landslide disaster reduction.
