| 摘 要： | 2008年西藏发生了4次Ms6.0以上地震,即1月9日改则Ms6.9地震、 8月25日仲巴Ms6.8地震、 9月25日仲巴县Ms6.0地震、 10月6日当雄Ms6.6地震. 通过检查和分析拉萨台观测资料,发现在这四次中强地震前都记录到了明显的地电场异常信号. 对于远震,震级和最大异常幅度与震中距乘积的对数存在着线性关系...

| Abstract: | In 2008,four MS6.0 earthquakes occurred in Tibet,i.e.the Jan.9 Gaize MS6.9,the Aug.25 Zhongba MS6.8,the Sep.Zhongba county MS6.0 and the Oct.6 Dangxiong MS6.6 earthquakes.By examing and analysing data from Lhasa station,we found that there are obvious abnormal geoelectric signals before these four moderate-strong earthquakes.For far earthquakes,the earthquake magnitude is linearly related to the logorithm of the product of abnormaly and epicentral distance,and in the time period of anomaly before earthquake... |
