晋冀豫交界地震定位和一维速度模型研究
Earthquake Positioning and 1D Velocity Model Research in the Juncture of Shanxi, Hebei, and Henan Provinces
摘要
Abstract
Based on the 994 P wave arrival times of 165 earthquakes occurred in Henan province and its neighboring area recorded by the Henan seismic network and 1D velocity model method,the paper got a relatively stable P wave 1d Minimum velocity model,stations correction and accurate earthquake through simultaneous inversion of epicenter and 1D P-wave velocity structure.The results show that earthquakes concentrated in the Linxian fault and Cixian fault,and earthquakes distribution is consistent with the strike of fault;station correction value are mostly positive in the mountains,indicating that there are low-speed material underground the mountains,while in AY,YON,XX,PY,QF station correction value is negative,indicating that the ground has high-speed material.关键词
