| Abstract: | The field gravity measurements in Xichuang region were carried out from 1990 to 2005.The observation network covers the fault belts,which are Anninhe and Zemuhe seismic faults.In this paper 4 intervals observation results of field mobile gravity measurement between 1990 and 1995,1996 and 1997,1998 and 2003,2004 and 2005 are compared with each other and the evolution character are summarized. |
