Prediction method for origin time based on groundwater Rn slip change rate
【摘要】 介绍了水氡滑动变化率的计算公式 ,滑动变化率的演化与地震时间的统计关系 ,据此给出了水氡滑动变化率值发震时间预测的步骤、判断指标和方法。结合震例 ,对预测效能进行了评价。检验性预测结果表明 ,预测的发震期限为 1~ 1 2个月 ,平均 5.1个月。该方法可以用于强震中短期预报
【Abstract】 This paper introduced the computation formula of groundwater radon slip change rate, statistical relation between slip change rate evolution and origin time of earthquake occurrence, on this basis, the step of origin time prediction by using groundwater radon slip change rate value, judgement index and method are given. Combining the earthquake cases, the prediction efficiency is evaluated, result indicates that the predicted origin time range is 1~12 month, the average is 5.1 month. This method may apply to medium and short term earthquake prediction.
