Focal mechanisms of Wen'an Mw 5.1 earthquake in Hebei Province in 2006
摘要
Abstract
Based on the records of 7 stations in Hebei seismic network,we inverted the focal mechanism of Wen'an Mw 5.1 earthquake on July 4 2006 with the "Cut and Paste"(CAP) method,and analyzed the seismogenic structure combining with the geological background.Our result shows that the best double couple solution of the Mw 5.1 earthquake is 215°,87° and-115° for strike,dip and rake angles,respectively.Another nodal plane solution is 118°,25 ° and-8 °.The geologic structure shows that the seismic fault in the north east concealed fault,properties with fault and strike-slip faults.This result is consistent with other research findings.关键词
