| Abstract: | Based on re calculating to the portable gravimetric data in Guangdong area from 1988 to 1999, the evolution tendencies of the gravity field in the eastern and western regions of Guangdong and the Pearl River Delta area have been analyzed.The relation between the gravitational field and the seismicity in coast area of South China has been discussed, and the earthquake precursory information for the time-space and strength changes of the gravity field in Guangdong area have been picked to provide the criterions of the gravity anomaly before earthquakes in this area. |
