| Abstract: | In the article, the anomalous variations of the helium content of the 4th observational well, the micro current of the-lth well in Lindian, and the water temperature at Daqing well in Heilongjiang province before the Lindian Ms 5.1 earthquake on July 25 2005 and Fuyu M 3, 7 earthquake on February 23 2005 are analyzed. The anomalous variations of microcurrent before this two earthquakes are obvious. The anomalous amplitude is 10-20 times higher than that of ordinary background. And the helium content anomaly before the Lindian Ms 5.1 earthquake is also notable. |
