| Abstract: | In this paper,the relationship between Shanxi seismic belt fault deformation features and strong earthquake preparation and occurrence is systematically analyzed and studied by analysing group fault anomalies before two earthquakes,1989 M6.1 Datong-Yanggao earthquake and 1998 M6.2 Zhangbei earthquake,based the whole historical leveling data measured across faults on the belt.The relative characteristics of fault deformation in space and time are pointed out,and it can be referenced in tracking the development of the future earthquake situation for earthquake prediction and research works with experiences from earthquake samples.At the same time,suggestions and views on the current North China earthquake situation,especially for tracking the earthquake situation on the Shanxi seismic belt are put forward. |
