Abstract

An earthquake of M_S8.0 hit Wenchuan, Sichuan, on May 12, 2008 at 2:28 p.m.Beijing time, which brought serious disasters and great loss of property to the people of the earthquake-hit areas.Especially the serious consequence that the earthquake-induced geohazards in mountainous areas caused was unexpected.This paper mainly reports the primary investigation results of the earthquake-induced geohazards in some worst-hit mountainous areas near the epicenter in Sichuan, briefly describes the characteristics of development and harm of earthquake-induced geohazards such as landslide, rockfalls, debris flow, ground fissures and sand-soil liquation and presents some ideas about the development mechanisms of earthquake-induced geohazards and problems that need to be further studied.All these have certain significance for guiding the reconstruction of earthquake-hit areas and planning cities and towns in high-intensity areas.
