The comprehensive analysis of earthquake precursors significance of the LuanxianML 3.3 earthquake swarm on January 11, 2015
摘要
Abstract
There is aML 3.3 earthquake swarm occurred in Luanxian,Hebei Province on January 11, 2015, which can locate earthquakes more than 200 times. We discuss the earthquake swarm and prediction of subsequent strong aftershocks using a variety of traditional and digital methods, such as the sequence parameters, the accurate location, the focal mechanism, the analogy with historical earthquake activity, the seismogenic structure and so on. The result shows that the earthquake swarm is still aftershocks of old earthquake, does not have the characters of foreshock sequence and typical precursory earthquake swarm. Tangshan as the aftershock window has not reached the window index. The accurate location results and focal mechanism solutions shows that theML 3.3 earthquake swarm occurred within earthquake empty section ofM 4, earthquakes after theML 3.2 earthquake on March 22th has not sustained development of this earthquake swarm.关键词
