Its epi center is located at latitude 33. 2 N and longitude 6. 6E, w ith hypocenter around 14km deep. A fter Yushu earthquake, using the emp iricalmodel of the postearthquake fast loss assessment, w ith some statistical data and vu lnerability curves of building, rap id emergency assessmentsw ere mi plemented, includ ing the experience isoseis m ic zon ing map and prelmi inary loss assessment resu lts. Comparedw ith the final survey results, the accuracy of the loss assessment resultsw as satisfactory. For further mi proving the assessment accuracy of the empiricalmodels, it is also argued that some empiricalmodel need be enhanced, includ ing the fau lt rupturemodel, ground motion attenu ation relationship mode,l vulnerab ility model of bu ild ings, and the forecasting model of t
