摘要
本文归纳了德都中强地震发生前湾_1井水位动态异变的基本特征,指出湾,井水位的四步段映震异常:骤然陡降—缓慢回升—高位跳动—高位稳定发震。并对短、临异常作了对比分析,探讨四步段映震异常对地震短临预报的重要意义。还就区域应力异常场和灵敏性问题进行了讨论。
This paper concluded the basic characteristics of the dynamic anomaly of the water level in Wan no. 1 well before occurrence of Dedu moderate earthquake and pointed out the four-step anomaly reflecting earthquakes of water level in Wan no. 1 well: steeply sudden drop-slow elevation-jumping at high level-stable earthquake occurrence at high level. Author also conducted the comparative analysis on the short-term and impending anomalies and discussed the important significance of the four-step anomaly reflecting earthquakes of the short-term and impending earthquake prediction. The problems concerned with the anomaly field of the regional stress and sensitivity were also discussed.
