This volcano was producing Boninite lavas – believed to be among the hottest erupting on Earth. Scientists also witnessed molten lava flowing across the deep-ocean sea floor and spotted shrimp living near the volcano’s most active areas. This research allows us to closely examine how ocean islands and undersea volcanoes are born.
