Feb. 9 (UPI) -- A trio of surveys carried out by scientists with the Kobe Ocean Bottom Exploration Center in Japan has confirmed the presence of a giant lava dome in the Kikai Caldera, a mostly submerged caldera located south of Japan's main islands.
Kikai is one of Earth's largest post-caldera volcanoes. The latest research -- published Friday in the journal Science Advances -- a giant lava dome has developed since the volcano's massive eruption some 7,300 years ago.
