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.
