摘要

2006年4月3日至9月19日在山西代县发生一次3.7级震群,着重研究该震群活动的时序列特征、韵律特征及震源机制解等相关参数。进一步探讨其对周围地区中强震的指示意义。分析结果表明,此次震群活动是该区域一次正常的地震起伏,并与周围350 km范围内华北地区中强震有较好的呼应关系。
There was an earthquake swarm of 3.7 in Daixian of Shanxi,lasting form Apr.3th to Sep.19 of 2006.In this paper,some parameters,such as sequence characteristics,rhythm characteristics and focal mechanism solutions etc.,of this earthquake swarm are mainly studied,to see if which are of indicating function for medium strong earthquakes around.The analytical result shows that this earthquake swarm activity is only a normal earthquake fluctuation in this area,which corresponds to medium strong earthquakes within 350 km around it in the North China.
