Abstract

Fast inversion for the rupturing process of the 20 April 2013 Lushan,Ya′an earthquake was conducted about 3 hours after the earthquake occurrence by using the GSN teleseismic waveform data.The obtained moment magnitude is MW6.8.It included two sub-events during the rupturing process,which occurred near the hypocenter or rupture initiation point and did not show significant rupture direction.The rupture of the earthquake did not break through the ground surface,and seismic disaster is concentrated on the hanging wall of the fault,around Lushan county and Baoxing county of Sichuan Province.
