Abstract Throng the studies on the seismic region (ML=73/4) shaking in 1947 at Dart Qinghai with the multitemporal aerospace remote sensing data, It was showed that the NWWlinear structure in the area played a dominant role in Dari’s earthquake, and the near EWblind fault appeares on the enhanced Landsat image of Sang Rima basin, Dart, and the ring image of Pingding mountain was considered to be a huge concealed rock mass with the aid of the aeromagnetic surveying data. According to the Dari’s seismic structure inferred, the seismic process can be explained well, and the basis for determining macroscope epicentre was provided.
