| 摘 要： | 大姚数字化水温自2008年开始观测,通过对水温分钟值动态特征分析,结果表明大姚水温动态在川滇菱形块体和滇缅弧发生7.0级以上地震前会出现基值大幅度下降、周期变化形态消失的异常特征,均为短临异常.异常指标对预测川滇菱形块体和滇缅弧发生强震有较高的实用性.进而初步探讨了大姚数字化水温分钟值强震前动态特征的成因.

| Abstract: | The borehole digital groundwater temperature measurement of Dayao starts from 2008. By analyzing the groundwater temperature with minutely resolution, the result shows that groundwater temperature decrease greatly and the periodical changes disappear before the earthquakes bigger than 7.0 in Yunnan-Sichuan block and Yun- nan-Myanmar arc. These indicators are useful in predicting strong earthquakes in Yunnan-Sichuan block and Yunnan-Myanmar arc. Futher more, the mechanism of these anomalies is also discussed. |
