Abstract

This work estimated the coseismic deformation field of the Yushu earthquake in 2010 using the C band ASAR data, and inverted the fault slip distributions and simulated the interferograms. The results demonstrated that the slip distributions were mainly presented in shallow depth above 15km.There were two slip-concentration areas, maximum slip was nearby the Jiegu town, and fault motion sense was left-lateral strike-slip, which were all reconciled with field observations.
