【摘要】 分析了甘肃省清水温泉与临夏水温观测井自2007年以来的水温观测数据,得出这两口井在2008年汶川8.0级地震前后有明显的异常变化。进一步用一元线性回归法、斜率K值法和从属函数法对每口井的水温异常信息进行了定量分析,更好地提取了地震异常信息。更多还原

【Abstract】 Analyzing the temperature observation data in Qingshui hot spring and Linxia water temperature observation well in Gansu Province since 2007,we found that there was obvious water temperature anomaly variation in two wells before and after Wenchuan M S8.0 earthquake on May.12,2008.We did the quantitative analysis on water temperature anomaly information of each well by a linear regression method,slope k-value method and subordinate function method,and extracted the better seismic anomaly information.These methods have important effect on processing and analyzing earthquake precursor observation data in long trend drift up(down) type,and are a newway to predict earthquake by using water temperature data for the future.更多还原
