摘　　要：2019年镜泊湖火山台网新增2个测震台,本文将利用火山台网5个火山测震台观测数据,对其进行噪声功率谱和监测能力计算,绘制震级监测能力图,使台网监测能力更加直观的展现,并且通过对火山活动性进行分析,为后续地震应急、监测预报等研究工作提供研究基础和技术参考。Two new seismic stations have been built in Jingpohu volcano network in 2019.In this paper,data acquired at 5 volcanic seismostations in the volcanic network was employed to estimate its noise power spectrum and monitoring capability.Map of magnitude monitoring capacity was drawn based on current data as well,which makes the monitoring capacity of the network more intuitive.Moreover,the analysis of volcanic activity was performed,which provided research basis and technical reference for follow-up earthquake emergency response,monitoring and prediction.

关 键 词：镜泊湖火山台网 噪声功率谱 监测能力 火山活动性
