Application of high resolution remote sensing technique to exploration of active fault of Hangzhou and its surroundings

It is important to explore the active faults in urban area and its surroundings for the earthquake disaster mitigation.Satellite remote sensing technique can play an important role in active fault exploration.In this paper we take Hangzhou as an example,introduce the treatment of extracting buried active fault information covered by Quaternary unconsolidated sediments.The result shows that it is feasible to explore the active faults in weak active structural area by using satellite remote sensing technique.
