GENERAL CHARACTERISTICS OF 5.12 EARTHQUAKE-INDUCED GEOHAZARDS IN SICHUAN

ZHANG Yong-shuang~(1,2),LEI Wei-zhi~(1,2),SHI Ju-song~(1,2),WU Shuren~(1,2),WANG Xian-li~(1,2)(1.Key Lab of Neotectonic Movement and Geohazards,Ministry of Land and Resources,Beijing 100081,China;2.Institute of Geomechanics,Chinese Academy of Geological Sciences,Beijing 100081,China)  
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.
