摘要

Abstract

Based on the ascending and descending orbit data from the LT-1 satellite and DEM,taking the MS7.1 earthquake occurred on January 23,2024,in Wushi County,Aksu Prefecture,Xinjiang Uygur Autonomous Region,as a case study,we used the two-pass differential interferometric synthetic aperture radar(DInSAR)technology to extract the co-seismic deformation fields of ascending and descending orbits in Wushi County,and compared with the results derived from Sentinel-1 satellite data,to verify the accuracy and reliability of geophysical field change information obtained by LT-1 satellite data before and after the earthquake.The results indicated that the maximum line-of-sight uplift amounts for the LT-1 satellite data during the Wushi County earthquake were 126 cm(ascending orbit)and 138 cm(descending orbit),while the maximum line-of-sight subsidence amounts were 13 cm(ascending orbit)and 33 cm(descending orbit),respectively.The deformation was mainly in the vertical direction,and the trend of co-seismic deformation field was generally consistent with the ascending orbit data from the Sentinel-1 satellite.
