The VEI scale begins at zero.

VEI等级从0开始。

The VEI scale does not have an upper limit.

VEI等级没有上限。

At a VEI of 6, an eruption can change the world.

在VEI六级，一个爆发能够改变世界。

Mount Tambora, a large stratovolcano erupted with a VEI measurement of 7.

一座巨大的层状火山，坦博拉火山爆发了，VEI等级为7级。

A VEI 2 eruption would fill four hundred full Olympic swimming pools with lava.

一个VEI二级的喷发能用熔岩填满四百座奥林匹克游泳池。

But the most catastrophic eruptions measured thus far are categorized as VEI 8.

但迄今为止测量到的最具灾难性的火山爆发被归为VEI 8级。

The most catastrophic eruptions ranking at VEI 8 happened thousands and millions of years ago.

最具灾难性的爆发是发生在数千万年前，火山爆发指数达到 8 级。

On the volcanic explosivity index, the 1815 eruption of Mt. Tambora earned the highest ranking ever recorded with a VEI 7 classification.

根据火山爆发性指数，1815 年坦博拉火山的爆发以 7 级火山爆发指数获有史以来的最高排名。

At VEI 7, we get Super-Colossal eruptions, millennium-defining events that human civilization has only encountered a handful of times.

在VEI七级，我们见识到的是超巨大爆发，这种定义千年的事件人类文明目前只经历过几次。

At VEI 5, we see catastrophic amounts of materials, cubic kilometers of debris, equivalent to an entire lake of molten rock blasted into the air.

在VEI五级，我们看到灾难性数量的物质、好几立方公里的碎片以及相当于一座湖的熔岩喷发到空中。

The chance of a VEI 8 eruption in the next few hundred years is less than 2% and more importantly, it would not come as a sudden surprise.

接下来数百年会发生VEI八级火山喷发的机率低于百分之二，更重要的是，这类喷发不会突如其来的发生。

At VEI 3 we already see devastating effects, like the eruption of the Semeru volcano in 2021 that destroyed thousands of homes in Indonesia.

在VEI三级，我们已看到毁灭性的影响，如在2021年的塞梅鲁火山喷发，摧毁了印度尼西亚数千所房屋。

Scientists love to put big booms on a scale and came up with a logarithmic scale that measures the volume ejected during an eruption: The Volcanic Explosivity Index, or VEI.

科学家们喜欢把大爆发放在一个刻度上，并提出了一个对数刻度来测量火山喷发期间所喷出的体积：火山爆发指数，又称VEI。
