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.
