摘要
概述了依安102井水位、声响的映震异常特点,指出了异常水位、异常声响,并非人为因素造成,不受大气降水过程的干扰影响,提出了孕发地震的区域应力—应变异常场同映震水位、映震声响之间,存在着内在的密切联系,结论认为,依安102井的水位异常、声响异常,同孕发德都地震的应力—应变区域异常相呼应,依安102井所在地处于德都地震孕震应力场直接影响范围。
Having summarized precursory features of water level and sound of Yian well No. 102 to reflect earthquake, we point out that anomalous level and sound is not man—made and is due to regional stress—strain field.
