摘要
分析研究了 1970年以来甘东南甘青川交界地区Ms≥ 5 0级地震前中小地震时空演化过程。结果指出 ,该区中强地震前地震活动在时、空、强等方面存在较为广泛的共性特征 ,对区域震情判定。
The evolution in spatio-temporal of middle-small earthquakes before ones with Ms≥5.0 in east-southern Gansu province and its neighbor regions since 1970 have been studied.The results show that the mutual features exist aboardly in spacial,temporal and intensity before the main shock,and they have a practice value for analysis and diagnosis in local earthquake prediction.
