石泉M_L4.7级地震前天水深井水温的短临异常特征
SHORT-IMPENDING ANOMALOUS CHARACTERISTICS OF WATER TEMPERATURE IN DEEP WELL BEFORE SHIQUAN EARIHQUAKE WITH M_L4.7
【摘要】 分析了天水台数字深井水温资料在陕西石泉ML4 7级地震前的异常特征,发现在震前5天内深井水温发生大幅度的降升变化,呈负脉冲形态,表现为典型的脉冲型前兆异常形态特征。
【Abstract】 Digital data of water temperature in deep well are analyzed,and found that great changes of the water temperatures five days before Shiquan earthquake with M_L4.7,presented negative pulse,and the characteristics are typical pulse precursory anomalies.
