Volcanic eruptions are measured on the Volcanic Explosivity Index, which goes from 0 (weakest) to 8 (strongest).
火山爆发用来衡量，这个指数从0(最弱)到8(最强)。
An eight-point scale called the "volcanic explosivity index" (VEI) allows you to compare eruptions and volcanoes.
你可以通过“火山爆发指数”(VEI)来比较喷发和火山，它把火山爆发分为8个等级。
Only one explosion in recent history has made it to 7 on the Volcanic Explosivity Index – 10 times bigger than Krakatoa.
在近代历史上只有一次火山爆发达到了7级的火山爆发强度指数，它的爆炸力是喀拉喀托火山爆发的10倍。
Kikai weighed in at 7 on the standard volcanic explosivity index (VEI), which runs from 1 to 8, VEI 8 being reserved for the sort of mega-eruptions that cause ice ages and mass extinctions.
Kikai火山的标准火山爆炸性指数(VEI)为7。ve I分为1到8八个等级，而VEI 8则用来描述那种造成冰期和大规模灭绝的火山爆发。
