Seismogenic Structure of 2016 Dinggyê MW 5.3 Earthquake, Tibet, Inferred from InSAR Observations
Abstract In this paper, we utilize Sentinel-1A SAR data and D-InSAR technology to obtain the coseismic deformation, inverse the fault geometry, and coseismic slip distribution of the 22 May, 2016 Dinggyê MW5.3 earthquake. The results show that the seismogenic structure is a NS strike normal fault with dip angle 43°,surface trend east and rupture length 9 km. The coseismic slip mainly occurs within 2-5 km, with a maximum slip of 0.24 m; the moment magnitude is MW5.3. The coseismic fault of the 2016 Dinggyê earthquake is a new blind normal fault in the Dinggyê-Shenza normal fault system.
