The Yushu Ms 7.1 earthquake was happened at 7:49:40.7 on April 14, 2010 in Yushu county of Qinghai province. Field investigation and analysis indicate that the Yushu segment of GanziYushu fault is the earthquake causing fault. The total rupture length caused by the Yushu earthquake is 23 km with a strike direction of NWWNW. The rupture is mainly characterized by leftlateral slipping, which can be further divided into three segments. The west segment is a continuous leftlateral slipping rupture, near the site, named Guoyangyansongduo, of Longbao town (33°03′11″N, 96°51′26″E), the horizontal offsets of the rupture is 1.75m, which is the largest amount measured, so the authors regard this area is the macroscopical epicenter. The middle segment is mainly located at the south of the city town, and composed by several rightstep subruptures. The east segment is mainly characterized by thrusting associated with leftlateral strikeslipping. Besides a large amount of house ruining, the Yushu earthquake has caused a series of secondary geohazards, such as sand soil liquefaction and related road deformation, earthquakeinduced landslides, aqueduct damaged by the earthquake and related soil landslide and mudflow, etc. After comprehensive analysis of the endogenic and exogenic geohazards, proposals have been given forth for fault avoidance and reconstruction site selection in the Yushu earthquake stroked area.
