On the basis of the geological structure setting in epicenter area，active faults，focal mechanism，the rupture process，the Western experience attenuation of ground motion parameter relations，and local site effects， ShakeMap of the April 14，2010 Yushu earthquake with magnitude 7. 1，Qinghai Province was obtained by prompt generation method of ShakeMap with the site effect． In about 2 hours after the earthquake occurrance，we provide it to the relevant departments． The results of Yushu earthquake ShakeMap show that the seismic intensity characteristics of our prediction are as follows: ① intensity distribution is the NW-SE direction， consistent with the strike of Yushu fault; ② maximum intensity is Ⅸ with an intensity area about 300km2 ; ③ extent of intensity Ⅸ mainly located between about 40km northwest of epicenter along the fault and 15km southeast of epicenter along the fault; ④ because of local site conditions in the northwest of intensity Ⅸarea，the intensity is reduced from Ⅸ on the bedrock to Ⅷ on the soil; ⑤ the area of intensity Ⅷ is about 3000km2 ; ⑥ the area of intensity Ⅶ is about 8000km2 ; ⑦ the area of intensity Ⅵ is about 24000km2 ．
