| Abstract: | By use of mobile gravity data in the northern area of Anhui province during 2005-2007,the dynamical gravity variation features before and after Dingyuan ML4.7 earthquake are analyzed.The results show that Dingyuan earthquake occurred in the high gradient zone of gravity variation near the area with high negative gravity variation.Before the earthquake,the gravity values around epicenter decreased,at the same time the high gravity gradient belt came into being along active faults;after the earthquake,the gra... |
