Research on Application of Remote Sensing Image Matching Technology in Earthquake Deformation Monitoring

Aiming at the defects of traditional ground observation technology, GPS technology and D-In-SAR technology in earthquake deformation monitoring, it puts forward the application of sensing image matching technology to earthquake deformation monitoring. It analyzes the basic principle and implementation method of optical image matching technology and uses this technology to the Mw 7.1 earthquake deformation monitoring of the Hector mine area in California of America. The test shows that these monitoring results of fault location and surface rupture are basically consistent with?field investigation ones.
