震前宏观异常是地震短临预报的重要依据之一.本文对山东地区39个有感地震前地下水、动物异常反应进行了统计分析.结果表明它们在时间、空间、数最和种类上有一定规律性,地下水与动物异常的时空特征不尽相同.最后讨论了宏观异常在地震预报中的作用.
The macro-anomaly before the earthquake is one of the important evidences for the short-term and short-term earthquake prediction.This paper makes a statistical analysis of the groundwater and animal anomalies before the 39 earthquakes in Shandong Province.The results show that they have a certain amount of time, space, Regularity, groundwater and animal anomalies have different spatial and temporal characteristics.Finally, the role of macro anomaly in earthquake prediction is discussed.
