江苏省部分地震台站CMG-3TB地震计监测能力对比分析

Analysis on Monitoring Capability of CMG-3TB Seismometer at Some Seismic Stations in Jiangsu Province

摘要: 选取了溧阳台、南通台和盐城台作为研究样本,以清晰可辨震相的记录幅值与脉动记录幅值的比值为标准,根据近震震级公式,用量规函数反推单台控制距离,分别计算出三台的监测能力,同时使用绘制地震震中分布图方法对计算出的理论监测能力结果进行了验证,更科学地反映CMG-3TB井下地震计的性能。

Abstract: This article selects CMG-3TB seismometer at three seismic stations of Liyang, Nantong and Yancheng as research samples, calculates the theoretical monitoring range of each station with the method of maximum amplitude ratio according to calibration function and local earthquake magnitude formula.At same time, the results are tested using epicenter distribution map in order to understand the performance of the CMG-3TB seismometer scientifically.
