| 摘 要： | 利用湖南省地震台网记录到的资料,研究了1970年以来湖南地区五次ML≥4.0级地震的地震视应变场的分布和时空演化特征.ML≥4.0以下的地震视应变与震级相关性较小,ML≥4.0以上地震的视应变值随震级增加呈非线形快速增大,说明:湖南地区地震视应变的时空演变与地震具有较好的对应关系.

| Abstract: | Using the events recorded by Hunan earthquake network, this paper studied the distribution and space-time evolution characteristis of the apparent strain for earthquakes with ML≥4.0 since 1970 in Hunan. The correlation of the earthquake apparent strain and magnitude is small for earthquakes with ML≥4.0. The apparent strain increased nonlinearly with magnitude quickly. The results show that the corresponding relationship between the space-time evolution of apparent strain and earthquake in Hunan is well. |
