It's the biggest eruption yet. The volcano came to life last week after 50 years of relative calm.
The revived Japanese volcano sent out giant plumes of ash and dust. The eruption also threw boulders for miles and broke windows five miles away.
The volcano is in a remote mountain range on the southern island of Kyushu. Public broadcaster NHK said a woman suffered cuts from shattered glass in Tuesday's blast. No serious injuries have been reported.
Geologists say there's a lava dome growing inside the crater, which signals more activity ahead.
