| 摘 要： | 本文通过对山东莒县井水位、水温资料的分析,认为莒县井水位、水温的异常典型模式为突降,异常多为远场大震的临震异常;远场大震的发生,是对莒县井孔区域应力的卸载。目前该区域的应力状态为拉张,对莒县井孔附近区域近期震情起到缓解作用。

| Abstract: | We analyzed the observation data of the groundwater level and temperature in Juxian County and found that a sudden jump seen from the data plots might result from a distant strong earthquake.So we consider it as a short impending precursory anomaly.These precursory anomalies reflect the tension stress state of Juxian County region. |
