Underwater Flare-up

Incredible video close-up of a deep underwater volcanic eruption taken by a small remote-control submersible. Here’s more.

And news coverage:

“…[T]his underwater activity has rarely been seen directly. Previous accounts were made either after the eruptions, or by surface vessels that couldn’t get close enough to the action.

In March 2004, a team of scientists from the National Oceanic and Atmospheric Administration sent a remotely operated research submarine named ROPOS to find some hot vents along the Mariana Arc volcanic chain.

“What we found was an eruption in progress,” said [one observer]. “We found this big pit with rocks and molten sulfur flying out. And we were sitting at the edge of this pit.”” (Fair and Impartial )
