| Abstract: | On April 14,2010 at 7:49(am),an M7.1 earthquake shook Yushu County,Qinghai Province.Its epicenter is located at latitude 33.2° N and longitude 96.6° E,with hypocenter around 14km deep.After Yushu earthquake,using the empirical model of the post-earthquake fast loss assessment,with some statistical data and vulnerability curves of building,rapid emergency assessments were implemented,including the experience isoseismic zoning map and preliminary loss assessment results.Compared with the final survey results,the accuracy of the loss assessment results was satisfactory.For further improving the assessment accuracy of the empirical models,it is also argued that some empirical model need be enhanced,including the fault rupture model,ground motion attenuation relationship model,vulnerability model of buildings,and the forecasting model of the casualties. |
