摘要
介绍了在2001年永胜6 0级地震前利用钻孔应变异常信息,结合岩石力学实验结果确定震中位置的过程,并在震前给出永胜地震的主压应力轴方向的思路,以及2002年布拖4 0级与巧家4 1级地震前利用跨断层形变测量异常,结合块体运动理论预测发震地段的方法。
Two new methods of forecasting earthquakes epicenter are introduced:(1)the accurate epicenter of 2001 Yongsheng M60 Earthquake was predicted by discriminating borehole-strain datas anomaly information and analyzing with rock mechanics experiments results.The direction of the earthquakes principle press axis was given before the shock.(2)The epicenter of 2002 Butuo M40 and Qiaojia M41 earthquakes were predicted by using deformation measure datas anomaly information and analyzing with sub-plate motion theory.
