地震过程是应变能积累与释放的结果。如何描述积累的程度并对出现的异常进行检测 ,一直缺少合理的定量化研究。通过对各项观测之间相关性的分析 ,讨论了地壳形变过程的异常强度指标 ,并进一步构造了异常强度的空间分布及其演化图像。与地震活动的联系表明 ,地震多发生在区域异常集中出现后的异常平静时 ,且远离异常集中区。并证实了地壳形变异常强度与地震应变能积累程度具有密切的相关性
Earthquake process is the result of strain energy accumulation and release. How to describe the degree of accumulation and detect abnormalities has been lack of reasonable quantitative research. Through the analysis of the correlation between the observations, the anomalous intensity index of crustal deformation process is discussed, and the spatial distribution of anomaly intensity and its evolution image are further constructed. The correlation with the seismic activity shows that the earthquakes mostly occurred when there was abnormal calm after the emergence of regional anomalies and were far away from the anomaly concentration areas. And confirmed that there is a close correlation between the anomalous intensity of crustal deformation and the accumulation of seismic strain energy
