A new volcano that erupted from the ocean last November and created it’s own small island has now grown to the point is has completely engulfed a neighboring volcano.

Niijima Island appeared out of the ocean in November and by the end of March created a landmass about a kilometer in length.  The island is now 200 feet above sea level at its tallest point and it continues to rise.

Scientists had initially said the island would disappear back into the ocean but now say it’s uncertain how large the island could grow until after the volcano stops erupting.

The island is located on the Pacific Ring of Fire and located about 600 miles south of Tokyo.
