"Stress triggering" between different rupture events in several earthquakes
摘要
Abstract
Most strong earthquakes have complex rupture processes.As an approximation,each earthquake can be described as two or more subevents of rupture with time interval of several seconds to several days. In order to discuss the telationship between different subevents,we investigated the rupture process of the 1966 Xingtai,the 1976 Tangshan,the 1990 Gonghe and the 1996Lijiang earthquake by calculating the static Coulomb failure stress changes produced by teh first subevent.The calculation of static stress changes produced by fault slip is based on the for-mulation of Okada(1992).The result suggests that the static Coulomb failure stress changes(△CFS)produced by the first subevent have "triggering"effect on the subsequent subevents which locate in the region where the coulomb stress change produced by the first event is positive,with the order of magnitude 10-2～10-1MPa.关键词
