贵州数字地震台网地震监测能力分析

Analyses on the Monitoring Capability of Guizhou Digital Seismological Information Network

贵州已经建立并运行14个数字地震监测台站。根据地震仪器的性能对贵州数字遥测地震台网的监测能力采用震级排序法进行理论计算,并利用2008年全年和2009年上半年的实测地震资料进行了检验。结论为贵州大部分地区能够监测≥ML2.1级地震,中部和东部部分地区≥ML1.9级地震,西部≥ML2.3级地震,北部地区监测能力较弱。

14 digital seismological information networks has been built and run in Guizhou province. According to the instrument capability, it used earthquake magnitude ranking method to do the theoretical calculation to the monitoring capability of Guizhou digital seismological information network, and testedit by use the observed earthquake information in 2008 and first half year of 2009. The conclusion is most area can monitor earthquake ≥ ML 2.1, central and part of eastern area ≥ ML 1.9, western area≥ML 2.3, the monitoring capability in north area is weaker.
