浅谈太原盆地的微震活动
|
摘要
通过对太原盆地近１０ａ来，遥测台网记录到的地震做震中分布、地震活动频度及能量释放等分析，得出太原盆地地震活动在时间分布上具有“丛集性”、盆地小震活动频繁、应变能释放常以小震群形式释放的结论。指出今后２ａ，太原盆地将出现地震活动频度高、应变能释放逐渐回升的现象。
Through the analysis for the epicentral distribution,the seismic frequency and the released energy of the earthquakes recorded by the telemetril seismic network in Taiyuan basin about 10 a,the conclusion was obtained that there is “cluster grouping of time” in the seismicity of Taiyuan basin,the small earthquake activity in the basin is frequently,the strain energy releases in the form of the small earthquake swarm.It was suggested that the seismic frequency and the released strain energy would be high in future 1～2 a.
