为了提高我国微小地震监测能力,"一带一路"项目拟在黑龙江鹤岗地区建设地震台阵。在2019年8月4日至9月4日,鹤岗地震台阵监测到部分近震及远震,与黑龙江省鹤岗地震台观测数据进行对比分析,得到以下结果:与鹤岗地震台相比,鹤岗地震台阵对近震及区域性地震的监测能力较高,对远震和极远震的监测范围较大,记录完整的地震个数更多,整体背景噪声更小,地震波形质量更高,定位更精确,提高了区域地震监测能力。
To improve microseismic monitoring capability in China, "The Belt and Road" Seismic Network Project is planning to build a seismic array in Hegang, Heilongjiang. From August 4 to September 4, 2019, Hegang Seismic Array detected some near earthquakes and distant earthquakes. Through comparative analysis with the observation data of Hegang Seismic Station in Heilongjiang Province, the following results are obtained:compared with Hegang Seismic Station, Hegang Seismic Array has a higher ability to monitor near earthquakes and regional earthquakes, has a larger monitoring range for distant and extremely distant earthquakes, and has more complete records of earthquakes. The overall background noise of the Hegang Seismic Array is smaller, the quality of the seismic waveform is higher, and the location results are more accurate, which improves the ability of regional seismic monitoring.
