New Volcanoes to Worry About

Just when you thought you only had to worry about volcanoes under the West Antarctica ice sheets, scientists had to go and discover more volcanoes off Antarctica. The British Antarctica Survey (BAS) recently released its finding of undersea volcanoes near the South Sandwich Islands in the Southern Ocean.

The volcanoes were discovered during research cruises through the use of ship-borne seismic mapping of the seafloor. The research cruises discovered 12 undersea volcanoes, along with craters left by collapsing volcanoes and 7 volcanoes visible above the sea. The volcanoes above the sea are active and some are up to 3,000 meters tall.
