汶川巨震与玉树强震地气系统演变的对比分析
A Comparative Analysis on the Evolution of Earth-gas System between Wenchuan Earthquake and Yushu Earthquake
摘要
Abstract
The monthly 3. 2 m-depth ground temperature and rainfall fields before the MS8. 0 Wen-chuan earthquake in 2008 and the MS7. 1 Yushu earthquake in 2010 are analyzed separately. The "earthquake-birth 3 steps" law are found also before the two cases. The time nodes for each step started in for the two respective earthquakes were Aug. 2006 and Jun. 2009 with a largest dry-hot area appeared for the first step, Jul. 2007 and Jul. 2009 with a strain wave beginning for the second step, and Mar. 2008 and Mar. 2010 with the strain wave ending for the third step. We had made an earthquake prediction for Yushu case according to the "earthquake-birth 3 steps" law in Nov. 2009, and the result showed that the magnitude forecasted was right but the location and the time were wrong. Therefore, though the "earthquake-birth 3 steps" is found, we still have a long way to make a prediction success.关键词
