Abstract:We determine the coseismic displacement of the Qinghai Zadoi MS6.2 earthquake that occurred on October 17, 2016 using ascending InSAR data from the ESA’s Sentinel-1A satellite, and we obtain the fault distribution of the earthquake using the SDM method. The results show that there is large dip-slip in the fault concentrating in the depth between 8 km and 12 km, with a little strike-slip component. The maximum slip of 0.17 m is observed at a depth of 9 km and is located near 32.85°N, 94.86°E. The obtained focal depth is consistent with the aftershock and the inverted seismic magnitude is MW5.9, which is consistent with the USGS and CENC.
