北京地磁测网调整与地震预测研究

READJUSTMENT OF GEOMAGNETIC SURVEY NETWORK AND RESEARCH ON EARTHQUAKE PREDICTION IN BEIJING AREA

摘要:

根据首都圈防震减灾示范区工程地震前兆流动观测系统的实施方案,2000~2001年开展了北京地磁测网的测点改造建设和优化;2001~2002年应用G-856磁力仪取得了准确可靠的资料.应用磁测资料分析了北京地区地磁变化,研究了震磁前兆信息,对开展地震监测预报工作有一定的实际效果与积极作用.对今后工作重点提出了建议.

Abstract:

According to the practice plan on mobile observation system of earthquake precursor for engineering of the anti-seismic and disaster-reduction demonstration area in the capital area, the sites of Beijing geomagnetic survey network were rebuilt and optimized during 2000~2001. The new network has obtained accurate and reliable data in the Beijing area during 2001~2002 by using G-856 magnetometers. Based on the data, the geomagnetic changes in the Beijing area were analyzed, the seismomagnetic precursor information was researched. The work has some practice effect to earthquake monitoring and prediction. At the end some suggestions for important work points in future are put forward.
