Title: SHAKEMAP OF PEAK GROUND ACCELERATION WITH BIAS CORRECTION FOR THE LUSHAN,SICHUAN EARTHQUAKE ON APRIL 20,2013
Abstract: After the Lushan,Sichuan earthquake on April 20,2013,based on the tectonic background,the distribution of active faults in the epicenter area,the focal mechanism solutions of this earthquake,the ground motion attenuation in western China and local site effect,ShakeMap of PGA was acquired.Then,distribution of PGA was amended by using PGA observations to correct system bias of theoretical estimates in the area without PGA observations.The results show that the vibration in epicenter area increased because the Lushan earthquake is a high-angle thrust earthquake.Especially,the vibration within 30km of the epicenter is more intense than the uncorrected results.
