摘要

通过对宁夏南部及邻区1965年以来ML≥3.0地震平静现象与中强地震的关系的分析和讨论,得到了宁夏南部4.9级以上地震发生前ML≥3.0地震的活动规律和4.9级以上地震的发生模式:平静1年→ML≥3.0地震活跃→平静4~6个月→发生地震,为今后宁夏南部的地震中短期预测提供了参考。
Most moderate earthquakes that occurred in Ningxia and its vicinity are isolated type ones,so it is difficult to give a good mid-,short-term and impendingearthquake prediction.In order to obtain the activity rule of(M_L≥3.0) earthquakes before moderate earthquakes,we study the relation between the quiescence of M_L≥3.0 earthquakes and M≥4.9 earthquakes in study area since 1965.The result shows that M≥4.9 earthquakes in Ningxia and its vicinity have following occurring mode: one-year quiescence → M_L≥3.0 earthquake activity → 4-6 month quiescence → M≥4.9 earthquakes occur.This mode provides reference for mid-,short-term and impending-earthquake prediction of study area.
