任何时候，只要是在冰川下面的火山爆发，都会有可能发生冰岛人所说的jokulhlaups .基本上，这是一种由快速融化的冰川水形成的巨大洪水。
Anytime there's an eruption under a glacier there's a lot of potential for what Icelanders call a jokulhlaups. It's basically just a giant flood of water from a rapidly melting glacier.
随着大量的水通过蒸发被抽离，并以雪的形式沉淀形成冰川冰，海洋中氧同位素的比率就发生了变化。
The oxygen isotope ratio of the ocean changes as a great deal of water is withdrawn from it by evaporation and is precipitated as snow to form glacial ice.
水还将逐渐减少，特别需要注意的是如果冰川形成屏障阻碍水流流动，那么冰川消融之后则会引发洪灾。
Flows may also get less regular, especially if glacial DAMS form, withholding water, and then collapse, causing floods.
