| 摘 要： | 大部分强震都发生在海沟,那里是海洋板块向大陆板块俯冲的地方.大量矩震级MW9.0以上的地震发生在若干区域,包括智利,阿拉斯加,堪察加半岛和苏门答腊岛等.位于太平洋板块俯冲鄂霍茨克板块的日本海沟,历史记载上没有发生过MW9.0地震,除了至今震级还有争议的公元869年Jogan大地震1](可能超过MW9.0).然而,根据...

| Abstract: | Most large earthquakes occur along an oceanic trench,where anoceanic plate subducts beneath a continental plate.Massive earthquakes with a moment magnitude,MW,of nine have been known to occur in only a few areas,including Chile,Alaska,Kamchatka and Sumatra.No historical records exist of a MW=9 earthquake along the Japan trench,where the Pacific plate subducts beneath the Okhotsk plate,with the possible exception of the AD 869 Jogan earthquake1],the magnitude of which has not been well constrained.However,t... |
