钻孔应变在新疆地震预报中的应用实践

APPLICATION OF BOREHOLE STRAIN IN EARTHQUAKE PREDICTION IN XINJIANG

简要总结了新疆十几年来，利用钻孔应变资料进行地震预报的实践。指出用钻孔应变资料预报地震是可能的，尤其是短临预报更是行之有效。实践证明打破年变规律是大震应变异常的主要特征。指数曲线是临震异常的具有规律性的可靠依据。压一张一发震的力学过程是应变异常的动态特点。

The authors have summarized briefly borehole strain data applied in earthquake prediction since ten years in Xingjiang. They point that it is possible for borehole strain datato predict earthquake, especially for short-impending prediction. The result shows thatbroken yearly change law is main feature of large earthquake strain anomaly. Index curve isa reliable basis of impending earthquake anomaly. The mechanical process of compressivestrain-tensional strain-earthquake is dynamic characteristic of strain anomaly.
