- Abstract:
-
Using the observation data of mobile gravity measurements in Shanxi-Hebei-Mongolia boreder area from 2013 to 2017,we recalculated all the data based on the adjust method. Then,we analyzed the spatial-temporal variation of the regional gravity field at different time periods. Finally,we discussed the earthquake prone regions based on gravity changes and deep tectonics. The result mainly shows that,the regional gravity anomaly appeared in the whole study region,forming gravity gradient zones consistent with tectonic faults,which may indicate tectonic movement or stress enhancement. We should pay attention to the potential earthquake risk in Datong-Zhangjiakou and Shijiazhuang-Xingtai area.
