断层形变异常识别与地震预测
Identification of Fault Deformation and Earthquake Predictions
【摘要】 在分析断层形变资料时,异常的识别和判定是一个重要环节。针对传统判定方法的不足之处,本文基于所谓异常就是对正常的某种程度背离,提出从“对象”和“状态”两个方面入手,提取不同种类、不同层次的断层活动异常,及时把握孕震过程中区域应力场的动态变化。震例研究表明,这种异常识别方法对地震预测而言是可行的。
【Abstract】 During analyzing fault deformation data,the judgment and recognition of anomalies are important steps.In view of the deficiency of traditional identification method,this article proposed that anomaly is something of the departure of variables from normal status.The anomalies of fault activities with different kinds and different levels can be identified from “objective” and “status”,thus the mobile changes of regional stress field can be observed.Case studies show that this identification method is useful to earthquake predictions.
