| 摘 要： | 针对华北地区40多年的地下水动态资料,分别依据从月均值、日值、分钟值等不同尺度资料中提取的具有可重复的代表不同时间特征的异常信息,进行多级地震预测研究.研究结果表明,华北中强地震之前区域地下水存在10年准周期特征,周期的上升和高值段可作为长趋势异常变化,在上升(或高值)趋势变化背景上存在3年左右的中短期下降异常变化,在...

| Abstract: | On basis of dynamic groundwater data in Northern China during the past 40 years, repeatability abnormal information represented characteristic of different time scales are extracted from data of monthly mean, daily mean and minutely mean respectively for the studying of multi-level earthquake prediction. The results show that before strong earthquakes, the groundwater in Northern China has a 10-year quasi period; the raising and high value segment of the quasi period may be a long trend abnormal change, in the raising and high value segment there are medium-short 3-year declining abnormal changes, short and im pending complex abnormality in different forms appears form 1 day to several months. These obvious re peatable abnormalities in different time scales can be used for multi-level earthquake prediction to strong earthquakes. |
