用缺震方法预报地震的探索

Research on Prediction Earthquake by Earthquake Absent Method

通过对山西境内１９８１年以来的ＭＬ≥２０地震，进行“缺震”、“过震”的统计，得出“过震”后不易发生较大地震，而“缺震”后会有较大地震发生的结论，指出用“缺震”方法进行地震预报具有一定的意义。把“缺震”作为常规预报指标，用于山西各区的地震预报研究，效果较好。

Through the statistics for “absent earthquakes” and “excessive earthquakes” of M L≥2 5 in Shanxi since 1981,the conclusion was obtained that the larger earthquake would not occur after “excessive earthquakes”,and the larger earthquake would occur after “absent earthquakes”.The earthquake absent method signifies to the earthquake prediction,taking the “absent earthquakes” as the routine prediction index to Shanxi,ist effect will be good.
