大庆地区地震精定位与震源机制解分析
Analysis of the fine location and focal mechanism solution of the earthquake in Daqing area
摘要
Abstract
Based on Daqing urban activity fault detection project,to carry out Daqing regional seismic activity research.When the seismic records of 662 earthquakes in Heilongjiang Province and the surrounding area were screened,the study area travel time model was revised.The results show that the seismic positioning accuracy is significantly improved after the double differential positioning,the spatial distribution of the earthquake is more concentrated,the strip shape is more obvious,and the depth of the source shows that the seismic potential of the study area is higher than that in the study area.The layer is located in the upper part of the crust.Based on the analysis of the tectonic stress field,the main compressive stress of the tectonic stress field in this area is NE direction,and the horizontal strike-slip effect is the main factor.关键词
