摘要
2019年镜泊湖火山测震台网新增2个测震台后,共有5个测震观测子台对火山区进行地震监测。利用其观测数据,进行噪声功率谱和监测能力计算,绘制地震监测能力图,并与原测震台网监测能力进行对比分析。研究表明,镜泊湖火山测震台网监测能力得到很大提升,可满足火山地震监测需要。
After adding 2 seismic stations to the Jingpohu volcanic network in 2019,there are 5 seismic stations for seismic monitoring in the volcano area.In this paper,data acquired at 5 volcanic seismostations in the volcanic network was employed to calculate the noise power spectrum and evaluate its monitoring capability.The seismic monitoring capability map is drawn and compared with that of the original network.The results show that the monitoring capability of the Jingpohu volcanic network has been greatly improved,which has met the needs of volcano monitoring.
