据史料记载，这座火山最近一次喷发是在1877年。

The gas produces an explosive eruption that hurls clots of lava hundreds of feet into the air.

爆炸产生的气体喷发是在空中抛了几百英尺的熔岩凝结。

The volcanic activities might be of lower eruption frequency, short interval between volcanic eruption cycles, and relatively quiet eruption, occasionally accompanied by intensive explosive eruption.

火山活动具有喷发频率低、间隔时间短、以宁静的溢流式喷发为主间或伴随较强烈的爆发式喷发为特点。

They compared ash that was ejected in the early, explosive phase of the eruption with ash from a later, more typical eruption of the volcano.

他们比较了取自火山爆发期次的喷发早期的火山灰和取自典型火山喷发的喷发后期的火山灰。

Scientists are not expecting the eruption to end anytime soon but so far it has not been explosive.

科学家们没有期待火山喷发近期能够结束，但到目前为止，火山还没有爆发性喷发。

Nor is explosive power the only measure of a volcano's spitefulness. The eruption of Laki, an Icelandic volcanic fissure, in 1783 sent poisonous gases across Europe.

然而爆发力不是衡量火山威力的唯一标准。1783年，冰岛莱基的火山裂缝曾排出有毒气体，并使其遍布欧洲。

The eruption of the basalt magma was flooding rather than explosive.

玄武岩浆活动是喷溢型而不是喷发型。
