摘要
The Yushu Ms 7.1 earthquake was happened at 7:49 on April 14, 2010 in Yushu County of Qinghai Province. Besides continuous surface rupture and a large number of properties collapse, the types of geohazards induced by earthquake include rock fall, landslide, potential debris flow, etc. In addition, the geohazards can be aggravated by the earthquake-induced sandy soil liquefaction, as well as burst of a channel, in local areas. Based on field investigation and comparison of the geohazard data before and after the Yushu earthquake, the authors summarize the major characteristics of the Yushu Ms7.1 earthquake, such as the amount of geohazard increasing obviously after the earthquake, the distribution of geohazards controlled by the active faults, the low-position soil/colluvial landslides predominant, the effect of geohazard chain being notable, etc. Some proposals for geohazard control during reconstruction have been given forth in this paper.
