山西数字测震台网监测能力及其构造意义

Monitoring Ability and Tectonic Significance of Shanxi Digital Seismic Network

通过对山西数字测震台网不同时期的监测能力进行对比,发现,台网的监测能力在不断地提高。对山西省地区的监控能力达到2.0级,大同盆地、太原盆地的监控能力达到1.5级,忻定、临汾、运城盆地的监控能力达到1.5～2.0级。说明山西数字测震台网的建设从布局上侧重了对山西活动构造的监测,目前对山西大部分活动断裂带的监测能力都在1.5级,对今后的地震监测预报研究和防震减灾工作有着重要的意义。

Through contrast of monitoring abilities of the Shanxi Digital Seismic Network in different periods,it is found that monitoring ability of network has been improving continuously.The monitoring ability for the whole Shanxi province reaches the magnitude of 2.0,1.5 for Datong basin and Taiyuan basin and 1.5-2.0 for Xinding,Linfen,Yuncheng basin respectively,which illustrates that layout of the Shanxi Digital Seismic Network puts particular emphasis on monitoring of Shanxi active tectonics.At present,monitoring ability of most active fault zones of Shanxi reaches M1.5,which is important for earthquake monitoring and prediction study and earthquake prevention and disaster reduction for the future.
