圣海伦火山景观这是美国历史上死伤人数最多和对经济破坏最严重一次火山暴发(19阿拉斯加卡特迈火山暴发是美国历史上规模最大一次火山暴发)。圣海伦火山暴发造成57人死亡，250座住宅、47座桥梁、24公里铁路和300公里高速公路被摧毁。火山暴发引发大规模山崩使山海拔高度从暴发前2950米下降到了2550米，并形成了1.5公里宽、125米深马蹄形火山口。喷发出火山灰和碎屑体积到达了2.3立方公里，是历史记载中最大规模一次。即使与其它地质年代发生过火山暴发相比则有所逊色。MountSt.HelensKeysA.1)Becauseuntil1980,ithadbeenquietformorethanahundredyears.2)Itwasstrange.Nobirdsweresinging,andtheairwasstill.3)Hewasstandingnearthesummitandreportingtheeruptiononradio.B.Washington;35;1980;123;recreation;summit;tremors;smalleruptions;nodanger;1980;dust;ash;rocks;mud;40;peaceful;emptyScriptsMostvolcanoesarequiet.Theyrestpeacefullyforhundredsofyears.Noonepaysmuchattentiontothem.MountSt.Helenswasoneofthesevolcanoes.Until1980,itwasabeautifulrecreation消遣；
