Study on Buried Faults in the Weifang Urban Area

摘要

Buried faults in Weifang city and surrounding areas are studied with geophysical surveys such as shallow seismic survey and electrical exploration,and verified with engineering drilling. Six main faults are detected including the Yishui-Tangtou fault,Tangwu-Gegou fault,Hanting fault and Weixian fault,etc. The latest active age is determined by OSL,TL and ESR dating techniques. No active fault has been found so far in the Weifang urban area. Our results provide a scientific basis for land use and urban planning.
