【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.更多还原
