| Abstract: | The effect of air pressure,crustal deformation,rains,and underground water on observed gravity data is discussed.The reliability of the data is proved.The variation of gravity field before and after Linyi earthquake(July 11,1998)is analyzes with geological tectoinc data.Based on the variation on the gravity field and the seismicity of that area,the event was predicted. |

| Keywords: | anomalies of gravity seismicity earthquake prediction |
