Surprise! Underwater volcano off Oregon coast erupts

9 Aug 11 – Leaves layer of lava more than 12 feet thick and a mile across in some places.

The eruption opened up new deep vents that are now belching forth “a cloudy stew of hot water and microbes from deep inside the Earth.”

In addition to producing lakes of lava, in places more than a mile across, the eruption changed the configuration of the region’s seafloor hot springs.

“There are more vents, they’re higher temperature,”
