1·The island is huge fissure eruption of adjacent formation volcanic island.

各岛是从洋底巨大裂隙喷发形成的火山岛。

2·The eruption opened a 500-meter (2,000-foot) fissure, and also produced lava fountains that built several hills of bubble-filled lava rocks (scoria) along the vent.

这次火山喷发使山体产生了一个500米（2000英尺）的裂缝并导致了数个熔岩喷泉，它们在火山口周围形成了多个由泡沫填充岩（矿渣）组成的小山丘。

3·Based on analyzing the eruption and tiny aggregate effect of fly ash, the influence of fly ash on the shrinkage fissure of concrete is studied, caused by the plastic deformation, dry or temperature.

以粉煤灰的火山灰效应、微集料效应分析为基础，分析研究了粉煤灰对混凝土塑性收缩、干缩、自缩和温度收缩裂缝的影响。

4·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。
