| Abstract: | Using ten terms of mobile gravity data from 2005 to 2009 in Kashi-Jiashi area,we study the temporal and spatial dynamics of gravity field to find the seismic information,then we discuss the relation between the gravitational variation and the tectonmic activity and the relation between the gravitational variation and seimicity.We find that the variation of the gravitational field is related to the tectonic settings;in the stage of seimogenesis,a certain scope of regional gravitational anomaly appears.The gr... |
