At least seven people are missing after a volcano erupted in central Japan Saturday, catching dozens of mountain climbers by surprise.
Mount Ontake erupted this morning sending a thick gray cloud of ash into the sky.
At least 32 people suffered serious injuries, including seven who were unconscious.
At least forty people are stranded in areas rescue crews cannot reach.
People evacuated a mountain lodge and planes had to change routes to avoid the plumes of ash.
Japan's government warns debris could end up falling as far as 2.5 miles away.
Mount Ontake, about 130 miles west of Tokyo, sits on the border of Nagano and Gifu prefectures, on the main Japanese island of Honshu.
The volcano's last major eruption was in 1979.
