昆仑山口西8.1级地震前四川攀枝花仁和台钻孔应变及水位的临震异常

Impending anomalies of borehole strain and groundwater level at Renhe observatory before the 2001 Kunlunshan Pass M 8.1 Earthquake

在 2 0 0 1年 11月 14日昆仑山口西 8. 1级特大震发生前数日内 ,攀枝花仁和地震台钻孔应变测值与应变仪钻孔内的水位测值出现大幅临震异常。叙述了对异常的发现、判断与地震预测的过程。

The impending anomalies of borehole strain and groundwater level at Renhe observatory,Panzhihua City,Sichuan province,appeared a few dys before the 2001 Kunlunshan Pass M 8.1 Earthquake.The procedure of anomalies' finding,judging,and earthquake prediction are described in this paper.
