STUDY ON JIASHI STRONG EARTHQUAKE SWARM AREA BY InSAR
新疆伽师强震群区的InSAR观测研究

On the basis of ERS 1/2 SAR from ESA,the DInSAR interferograms of Jiashi strong earthquake swarm area during 1996-1999 are obtained by combining with high-precision SRTM digital height model-DEM by NASA of America.The results show that the seismic activities and crustal deformation in this area during 1996-1999 were effected by faults of EW and NEE and the motion difference between the southern and northern blocks of the Keping fault was about 5 mm/a(along the LOS trend).However the Jiashi Ms6.0 earthquake on aug.2,1998 and Ms6.6 earthquake on Aug.27 may not be related to buried fault.
