南投-花莲M_S7.6和岫岩-海城M_S5.4地震前后本溪井水位的异常变化

ANOMALOUS CHANGE OF THE WATER LEVEL FROM BENXI WELL BFORE AND AFTER NANTOU-HUALIANM_S7.6 AND XIUYAN-HAICHENG M_S5.4 EARTHQUAKE

总结了台湾南投-花莲MS7 6地震(1999 9 21)和岫岩-海城MS5 4地震(1999 11 29)前后本溪井水位的异常变化情况。认为此次台湾强震群活动导致辽宁地区地壳应变及应力场发生明显改变,是发生岫岩5 4级地震的重要起因。

The anomalous change of the water level from Benxi well before and after Nantou-Hualian earthquake of M_S7.6 on Sept.21,1999 and Xiuyan-Haicheng earthquake of M_S5.4 on Nov.29,1999 is summarized.It is considered that this strong earthquake swarm activity leads to change the strain and stress field in Liaoning area,which is one of the reasons of Xiuyan-Haicheng earthquake M_S5.4 occurred.
