| 摘 要： | 在四川开展水氡前兆观测的初期,部分水氡点的水氡测值突跳异常很好地对应了其可预测范围内的中强以上地震。水氡测值突跳异常曾作为松潘—平武和盐源—宁蒗等地震预报的重要依据。但在水氡观测至今的完整时间段内,水氡突跳异常总体表现出对应率低,漏报率高的现象。多次预报攻关研究结果显示,水氡观测的异常表现是多种多样的,水氡测值突跳异常只是其中的表现之一。在今后四川及邻区的中强以上地震预报实践中,水氡测值突跳异常仍可作为地震短临预报的重要参考。

| Abstract: | In the early period of observing the content of water radon in Sichuan Province,the value of water radon in some of observing points presented changes relative to medium-strong earthquakes occurred around.The water radon anomaly is taken as an important index to the earthquake prediction of Songpan-Pingwu in 1976.Analyzing the changes of water radon in the whole period from the beginning of water radon observation,we find that the whole corresponding rate(the water radon changes to earthquakes)is low.Further studies indicate that the anomaly changes are complicated and the water radon is only one index for the prediction of medium-strong earthquake in Sichuan Province. |
