本文通过对塔院井1984年7月—1985年6月水位微动态资料的系统处理,捕捉到88个微动态异常。在此基础上,分析了这些异常和同期大华北地区的地震活动的关系。结果表明,塔院井水位微动态在多数M_L≥4级地震前有异常反映,尤其在山西地震带的地震活动前反映较明显。因此,塔院井水位微动态分析有可能作为监测该带地震活动的重要途径之一。
In this paper, 88 micro-dynamic anomalies were captured by systematically processing the microtynamic data of water level from July 1984 to June 1985 in Taiyuan well. Based on this, the relationship between these anomalies and the seismic activity in North China during the same period is analyzed. The results show that the water level microturbation of the tower well is abnormally reflected before most M_L≥4 earthquakes, especially before the seismic activity in Shanxi Seismic Belt. Therefore, the micro-dynamic analysis of water level in Tarim well may be one of the important ways to monitor the seismic activity of the belt.
