Discovered by PMEL and University of Washington scientists in May 2009, West Mata volcano is the deepest erupting submarine volcano ever witnessed at 4000 feet below sea level. High definition footage of the volcano was released on December 17 that includes violent eruptions spewing lava and rocks into the sea. This volcano also marks the first time scientists have witnessed pillow lava forming new Earth right before their eyes.
