Based on the Previous research results,through the field seismic geology survey on the surface outcrop section of the target faults,and shallow seismic reflection exploration、drilling exploration crossing faults、trenching,and electromagnetic wave CT exploration of concealed faults,the spatial position and the Quaternary activity of target faults in Shenzhen City are identified,the distribution map of main faults in target zone is drafted.In addition,based on the regional tectonic background,the target faults＇ overall level of earthquake intensity is analyzed,and upper limit magnitude of the faults is educed,Then,the maximum magnitude of earthquakes in Shenzhen is evaluated with the Warehousing-Miyake empirical relationship and the tectonics analogy method.Finally,the seismic hazard of the target faults in Shenzhen is assessed comprehensively according to the methods above-mentioned.the risk evaluation map of target faults is drafted in this paper.
