北京地区震磁研究的进展与展望

Progress and prospect of seismomagnetic research in Beijing area

北京地区地磁观测网由 1 6条测线、1 5 0个测点与 1 6个临时台组成 ,取得了大量的准确可靠资料。应用这些资料 ,消除了地磁正常变化背景 ,分析研究了震磁前兆信息 ,获得了有意义的震磁前兆 ,在地震监测预报工作中具有积极作用与一定实效。与此相配合 ,开展了密云水库与活动断裂的构造磁学研究 ,为震磁前兆研究提供了有实用价值的结果 。

The geomagnetic network in Beijing area consists of 16 profiles, 150 sites and 16 temporary stations. A lot of precise and reliable data have been obtained in the network. Using these data, the normal change background of geomagnetic field was eliminated, and the seismomagnetic precursor information was analyzed and researched. The significant seismomagnetic precursor was obtained. Several earthquakes were well predicted, and it has active effect and some practical efficiency in earthquake monitoring and prediction work. Combining with this project, the tectono-magnetism research of the underground nuclear explosion, the Miyun reservoir and the active fault has been carried out, providing the results with practical value for seismomagnetic precursor study. Finally, this paper discusses and prospects the development prospects of seismomagnetic precursor research.
