东北地区ML≥4.0地震震源机制特征分析
Focal mechanism solution analys is of ML≥4.0 earthquakes in Northeast China
摘要
Abstract
Based on the seismic waveform data of ML≥4. 0 earthquakes happened in Northeast China from January 2008 to May 2010, we made an analysis of the focal mechanism of Northeast China with the use of P wave first motion data of neighboring provinces. Then together with the former acquisition, we studied the general characteristics of stress field direction and the variation of stress axis direction. We also analyzed the relationship between P axis variation against time and the possibility of moderately strong earthquakes happening in Northeast China.关键词
