- Abstract:
- Taking the coseismic deformation of Yunnan Mojiang MS5.9 earthquake in 2018 obtained from D-InSAR technology as a constraint,we inversed the slip distribution of the fault plane along the region tectonic by the steepest descent method(SDM)and discussed the seismogenic structure of the earthquake. The results indicate that the maximum deformation in LOS-trending caused by the Mojiang earthquake is about 6 cm,and the distribution of co-seismic deformation field is symmetrical. The seismic fault is dominated by right-lateral slip,which is consistent with the dextral tectonic movement background of the regional tectonic. The largest slip achieves 0.19 m,which is distributed about 10～13 km along the fault strike and 3～6 km down along the dip direction. The slip of fault near surface is small,and the coseismic displacement does not break to the surface.
