火山爆发是蕴藏在地球内部的无穷能量的大释放。在英语中,“火山(volcano)”是古罗马神话中火神的名字。火山爆发主要有两种形式。一是热点爆发。“热点”是指地壳上的一些管状通道。来自地幔的物质常常会通过这些通道涌出地面。当漂移的大陆板块移动到地壳热点上方时,地幔的熔岩便会从这些热点涌出,导致频繁的火山爆发。美国的夏威夷群岛火山群就是这类火山活动的表现。二是大陆地壳边缘 Volcanic eruptions are large releases of infinite energy contained within Earth’s interior.

The Hawaiian volcanoes in the United States are the manifestation of such volcanic activity. Second, the continental crust edge
