摘要
利用2015年1月1日—6月30日期间和田小孔径台阵记录到的地震活动,用swa软件的线性化反演方法对拾取到的地震信息进行波形分析定位,得出完整的人工地震目录表,并对表格里的信息做数据综合分析。用MSDP分析软件的单纯型定位方法,计算分析新疆台网的地震活动,并和新疆台网在台阵周边200km内这一特定区域所记录的地震信息做对比分析,得出和田小孔径台阵的监测能力。和田台阵地震监测能力下限已达到-2.19级,250km范围内可记录零级以下地震,500km内可记录小于1级地震,800km内可记录小于2级地震。
Based on the earthquake activities recorded by the Hetian small-aperture seismic array from January 1 to June 30,2015,in this study,we analyzed the waveforms and positioned the source of these events using the linear inversion method and the software swa to obtain a complete artificial earthquake catalog.Next,we used MSDP software and the simplex location method to compute and analyze the earthquake activities recorded by the Xinjiang Seismic Network.Then,we analyzed the seismic record of the Xinjiang Seismic Network within 200 km around the Hetian small-aperture seismic array and compared our results with those recorded by the array to determine the monitoring capacity of the Hetian small-aperture seismic array.Based on our results,we conclude that the low limit of the earthquake monitoring capacity in the Hetian array has a magnitude of-2.19,within a 500 km range its magnitude is less than 1;and within a 800 km range its magnitude is less than 2.
