深井水位气压效率和相关系数在中强地震前的变化特征
|
摘要
采用高阶差分求深井水位的气压效率和相关系数的方法并优选最佳相关结果 ,获得了 5口井在两次中强地震前二者的变化 .认为从这一方法中提取的短临异常信息是可行的 ,可以作为中强地震前的短临异常指标 .
The barometric pressure efficiency and interrelation coefficient of groundwater level in five deep wells are calculated by using high order difference method and the best interrelation result between them is optimized.The anomalous variations on two curves are obtained before the Heze 5.9 earthquake in 1983 and Lulong 5.3 earthquake in 1982.The result indicats that anomalous information obtained from the method is feasible,and can be used as short impending anomaly before moderate and strong earthquakes.
