Landslide dams triggered by the Wenchuan Earthquake, Sichuan Province, south west China
Abstract At 14:28 (Beijing time) on 12 May 2008, the catastrophic Ms 8.0 Wenchuan earthquake occurred just west of the Sichuan basin, China, causing severe damage and numerous casualties. It also triggered a large number of landslides, rock avalanches, debris flows etc. Some of the landslides formed natural dams in the rivers, with the potential secondary hazard of subsequent flooding. Through the interpretation of a series of aerial photographs and satellite images, 256 landslide dams were identified, although because of limited access, relatively detailed data were available for only 32. The paper presents statistical analyzes of the distribution, classification, characteristics, and hazard evaluation of these 32 dams. A case study of the 2.04 × $ 10^{7} $ $ m^{3} $ Tangjiashan landslide dam and the emergency mitigation measures undertaken is discussed.
