Abstract:We systematically analyzed 10 out of the 35 earthquake swarms in Ningxia and its adjacent area,summarized the characteristics of earthquake swarms and discussed the relationship between earthquake swarms and medium-strong M ≥ 5.0 earthquakes in Ningxia and its neighboring area since 1970. Swarm forecast is recommended for M ≥ 5.0 earthquakes in the Lingwu-Wuzhong region but not for MS ≥ 5.0 earthquakes in southern Ningxia and its neighboring area. Whether there is a subsequent medium-strong earthquake,the general effect of the swarm precursor discrimination is not very good and need the reference to other methods and means.
