摘要: 对1982年至1997年昌黎井的水氡、水位月均值和昌黎气象站的降雨资料,以不同的时间尺度进行了相关计算。结果表明, 水氡与水位资料的趋势变化具有很好的相关性(R=0.833, n=168)和同步性。较小时间尺度的相关计算结果显示,水位、水氡与降雨不仅具有相关性、同步性,而且也具有差异性,这种差异性特征可作为地震前兆异常,并与唐山地区的地震对应较好,据此可作为短期地震预报指标。

Abstract: In this paper, the data of monthly mean values for water radon and level of g round water in Changli well and the rainfall data of Changli meteorological observatory from 1982~1997 are calculated. The results show a very good correlation and synchronism in m any years among them, but some differences in small time scale. These differences are corresponding to local earthquakes very ell. Thus we can make the short-term earth-quake prediction based on these differences.
