TOKYO (AP) " A revived Japanese volcano threw boulders for miles and broke windows 5 miles away in its biggest explosion yet.
The blast sent a huge plume of gas and ash into the sky and officials widened the danger zone to keep residents away.
The eruption early Tuesday was the biggest since the Shinmoedake volcanoburst to life last week.
Wide areas were covered with ash and boulders landed on roads miles away. The blast also knocked down trees and broke hundreds of windows in local hotels and offices.
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.
