Report and vocabulary

Shimmering hot water seen coming out of an undersea volcano off the coast of Oregon.

During a routine visit to the area last month, researchers found lava coming out of a vent that was formed on the seafloor.

According to them it's the first successful forecast of an underwater eruption.
