| Abstract: | Gravity changes around the Wenchuan Ms8.0 strong earthquake are probed using the gravity data in many period of time from mobile gravimetric observation network which is located at junction area of Hebei, Shangdong and Henan province(Ji-Lu-Yu). The results revealed that in the period of earthquke preparation in a definited area there was a negative gravity anomaly whose maximum value was 43×10 -8 ms -2, nearly before the earthquake occuring and then gravity should be restored up after the earthquke. |
