0 Japanese volcano erupts

A volcano in southwestern Japan erupted Sunday after nearly two weeks of relative silence, sending ash and rocks up to four kilometres (two and a half miles) into the air, a local official says. 

It was not immediately clear if the eruption was a direct result of the massive 8.9-magnitude earthquake that rocked northern areas Friday, unleashing a fierce tsunami and sparking fears that more than 10,000 may have been killed.

Smoke rises from Shinmoedake peak, a mountain in the Kirishima volcanic range between Kagoshima and Miyazaki prefectures.

The 1,421-metre (4,689-feet) Shinmoedake volcano in the Kirishima range saw its first major eruption for 52 years in January. There had not been any major activity at the site since March 1.

Authorities have maintained a volcano warning at a level of three out of five, restricting access to the entire mountain.

In April last year, the eruption of the Eyjafjoell volcano in Iceland dispersed a vast cloud of ash, triggering a huge shutdown of airspace that affected more than 100,000 flights and eight million passengers.
