On December 18, at 23:59, a 6.2-magnitude earthquake struck Jiashishan County, Linxia Prefecture, Gansu province, at a depth of 10km. The co-seismic deformation field of the Jishi Mountain earthquake was obtained by using the interferometric SAR data before and after the earthquake of the latest landsat-1 satellite in our country. The pre-quake data were 2023 on December 18, and the post-quake data were 2023 on December 22. A four-day revisiting period ensured the high coherence of the interferograms. The results show that the earthquake caused obvious surface deformation, the largest uplift deformation magnitude of 7 cm, which is consistent with the nature of the earthquake thrust earthquake. The results provide important data support for scientific research on earthquake emergency response.
