One person was killed and at least 11 other people injured after a volcano erupted near a ski resort in Kusatsu, about 140 kilometers northwest of Tokyo, on January 23.

The eruption of Kusatsu-Shirane was followed by an avalanche that trapped about a dozen skiers, including six members of Japan’s Ground Self Defense Force who were training in the area, one of whom later died from his injuries, Reuters reported.
