| Abstract: | We have summarized the abnormal rules of volume Strain in Jinzhou Seismic Station before Zhangbei M 6.2 earthquake,Shenyang M 4.1,Inner Mongolia M 5.9,Japan M 8.0,Russia M 7.9,and Qinghai M 8.1.We had identified precursor of earthquake using some methods such as strain tides factor,three point smooth filter and so on.The results indicated that there was some correlation between the volume strain abnormality and earthquake occurrence. |
