| Abstract: | Annual gravity changes in China mainland and its vicinity are calculated from GRACE data,and the characteristics of annual changes are discussed.By analyzing the gravity changes before and after several strong earthquakes,the results show that the gravity in the epicenter zone appears positive before the earthquake and converts to negative after the shock.The calculation of the gravity before and after the Wenchuan earthquake shows the same phenomenon.It is concluded that the regional gravity field is affected by strong earthquakes,and gravity satellites have the ability of detecting gravity changes caused by strong earthquakes. |
| Keywords: | GRACE satellite gravity field gravity changes Wenchuan M_s8 0 earthquake earthquake monitoring |
