山东数字地震台网的监测能力

Monitoring Capacity of Shandong Digital Seismic Network

利用山东数字地震台网数字记录无震、无明显干扰事件情况下的44个台站背景噪声资料,计算了山东数字地震台网的监测能力,并利用"十五"台网试运行期间记录的爆破和地震事件进行检验,得出的计算结果与实际观测结果基本相符:鲁西地区、黄海和渤海海域的地震监测能力达到ML≥1.6,中东部地区地震监测能力达到ML≥1.3,胶东半岛部分地区和鲁南部分地区监测能力达到ML≥0.7。

The earthquake-monitoring capacity of Shandong digital seismic network is calculated by using the broadband digital data of background noise record of 44 stations when there is no earthquake record or other disturbance, and also inspected by using the blast and seismic records of the tenth five-year plan network during test operation. The calculation results are in accordance with actual observation. In addition, the results show that the earthquake monitoring capacity has realized ML ≥ 1.6 in Luxi area, Huanghai Sea and BohaiSea, ML ≥1.3 in central and east area, ML ≥0. 7 in some region of Jiaodong Peninsula and some parts of the South.
