Surprise Underwater Volcanic Eruption Discovered
Excellent 3D graphic representation of the lava. Note this particular volcano was previously report by Scarlet- yesterday.
“An undersea volcano has erupted off the coast of Oregon, spewing forth a layer of lava more than 12 feet (4 meters) thick in some places, and opening up deep vents that belch forth a cloudy stew of hot water and microbes from deep inside the Earth.
Scientists uncovered evidence of the early April eruption on a routine expedition in late July to the Axial Seamount, an underwater volcano that stands 250 miles (400 kilometers) off the Oregon coast.”
“At first we were really confused, and thought we were in the wrong place,” said Bill Chadwick, a geologist with Oregon State University. “Finally we figured out we were in the right place but the whole seafloor had changed, and that’s why we couldn’t recognize anything. All of a sudden it hit us that, wow, there had been an eruption. So it was very exciting.”
And in mid July, Voice of America reported:

First Large Antarctic Undersea Volcanoes Discovered in Southern Atlantic
A British research team has discovered a chain of 12 undersea volcanoes near the remote South Sandwich Islands in the southern Atlantic Ocean. It is the first group of large undersea volcanoes ever found in the Antarctic region.
Scientists from the British Antarctic Survey (BAS) say that seven of the massive volcanoes are still active. Some of the mountain peaks rise three kilometers above the ocean floor, nearly tall enough to break the water’s surface. The collapsed craters of others measure five kilometers across.
