【摘要】 通过对大姚高精度水温1986年观测以来100km范围内发生5 0级以上地震前后的水温动态特征分析,结果表明大姚水温动态在地方震前基值上升,周期变化形态消失或畸变,震时有同震反应,震后存在震后效应,水温动态具有震前异常变化明显且多为短临异常的特点,对观测井周围的地方震预测具有较高的实用价值。初步探讨了水温动态异常的可能原因。更多还原

【Abstract】 The precise observation of Dayiao ground water temperature began in 1986. The characteristic analysis between observation data and the earthquakes with magnitude M5.0 within the 100 km radius range are made. Our result shows that the temperature of ground water increase before a local earthquake and the annual cycle change disappear. The changes of temperature of ground water go with the local earthquakes. These changes are characterized by the short and impended abnormal changes. These short and impended abnormal changes can be of important value for earthquake forecast.更多还原
