There is currently some alarming activity happening inside a supervolcano that sits just 31 miles away from Southern Japan.
A paper published in Nature Scientific Reports says that a lava bubble is expanding inside of the Kikai Caldera, a massive underwater volcano.
More than 31 cubic kilometers of lava have pushed the seabed up around 2,000 feet, with the volcano's peak now resting only 98 feet below the ocean’s surface.
But the issue here is the bubbling cauldron of magma inside the supervolcano is starting to build up large amounts of pressure.
