Japan has one more island than they did yesterday. Maybe.
An undersea volcano has pushed up a circle island with a diameter of 660 feet. It's the first new island since the 1970s.
It's fairly likely that the small island will sink back under the waves - and because of that, Japanese authorities haven't named it. If it does stick around it will add a little bit to the land area of Japan, a country shaped and threatened by high levels of volcanic activity.
For once, geological activity might have done a good thing. Or at least a very, very cool one.
Video of the eruption can be found here.
