| 摘 要： | 以晋、冀、蒙三省交界地区的4次6级左右地震为例,研究了中期异常向短临异常演变的特征.此特征可由地震活动图象异常、地震平静与密集、信号震到加卸载响应比异常、日频次起伏加剧的演变来表征,在时间进程上它们是一个渐进的过程.

| Abstract: | Based on four strong earthquake examples in the common boundary of Hebei province,Shanxi province and The Inner Mongolia autonomous region,we studied the anomalies' evolutionary characters from medium term to short term.These characters can be expressed by seismicity's spatial image,quietness and active,response ratio of load unload and intensification in fluctuation of daily frequency.It is a gradual process with time. |
