Two hours after the 2010 Yushu Earthquake,the shaking intensity distribution was obtained using the ShakeMap Rapid Generation System Based on Site Effects,developed by the author,which integrates the information of tectonic settings,the strike and scale of causative faults,focal mechanism solutions.fault rupture process and attenuation relationship in Western China,as well as local site effects.The results are as follows:① The major axis of shaking intensity distribution is directed NW-SE,parallel to the Yushu fault;② The meizoseismal area reaches an intensity Ⅸ and covers 300km2;③ The intensity Ⅸ area is mainly distributed in the area 40km southeast and 15km northwest of the epicenter along the causative fault;④ Due to local soil conditions,the northwestern part of the area with intensity Ⅸ on bedrock shows an intensity Ⅷ when converting from the bedrock to the soil;⑤ Areas with intensity Ⅷ,Ⅶ,Ⅵ measure 3,000km2,8,000km2,and 24,000km2,respectively.
