A close-up look at a rare underwater eruption

More than 70 percent of all volcanic activity on Earth occurs on the seafloor, but details of these events are largely hidden from view by seawater. In 2015, scientists from the University of Tasmania, Woods Hole Oceanographic Institution, the University of California Berkeley, the University of Otago in New Zealand and others traveled to the site of an underwater volcanic eruption, the Havre Volcano in the Southwest Pacific Ocean. The team found that the eruption history of the Havre volcano was much more complicated than they previously thought, with the most recent eruption alone consisting of lava from 14 volcanic vent sites between 900 and 1220 meters (3000 and 4000 feet) below the surface.
