In volcanic activity, this is another one. And as I said, I've mentioned this on the net a few times. But there's more coming out about this now. There's a study presented at the Goldsmith International Geochemistry Conference just this past week. And it describes how ice sheets may have been involved in past volcanic activity. And they found that during the peak of the last ice age, 20,000 years ago, a thick layer of ice cover helped inject a huge reservoir of magma onto the Earth's surface. And it was about six to nine miles below that, around 9.6, about 14 kilometers, I think, below the surface. And at the end of the ice age, the ice sheets began to retreat. And a lot of ice weight let magma gases, allowed magma gases to extend. And that sent an emotional explosive eruption from brand new volcanoes just off it.
