Title: Relation between Earthquake Quiescence (M_L≥3.0) and Moderate Earthquakes in the South of Ningxia and Its Vicinity
Abstract: 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.
