- Abstract:
- The Akto MS6.7 earthquake,Xinjiang occurred near the western end of the Muji fault basin in the top of the Pamir syntax.The main shock of this earthquake is complicated and the focal mechanism solutions show differences based on seismic wave inversions.Based on the Sentinel-1 SAR image data,the coseismic deformation field of the earthquake is obtained by InSAR technique.Based on the elastic half-space dislocation model,the geometrical parameters and the slip distribution model are determined by nonlinear and linear inversion algorithms.The results show that the distributed slip model can well explain the coseismic deformation field.The earthquake includes at least two rupture events,which are located at 7 km(74.11 ° E,39.25 ° N)and 33 km(74.49 ° E,39.16 ° N)east of the epicenter of the CENC.The deformation field caused by the earthquake shows symmetric distributions,with the maximum deformation(LOS)of 20 cm.The main seismic slip is concentrated in the 0～20 km depth,and the maximum slip is 0.84 m.The seismic fault is the Muji fault,and this earthquake shows that the N-E thrust of the Indian plate is enhanced.
