Avalanche and volcano hit Japan ski resort

One person is missing after an avalanche at a Japanese ski resort which may have been triggered by a nearby volcanic eruption.

At least 10 people were also injured in the incident near Kusatsu in central Gunma prefecture, say officials.
Several people have been rescued, from the mountain Japanese media report.

Authorities say the Kusatsu-Shirane volcano erupted at the same time, but it is not yet clear whether the avalanche was triggered by that.

"Based on various measurements, we can say that the mountain appears to have erupted, but we are still trying to confirm facts on the ground," Japans Meteorological Agency said, according to Reuters.

Authorities have warned people not climb the mountain.

Japanese media have broadcast footage showing rocks flying through the air.

Four people who were riding a gondola at the resort at the time were among the injured, say the reports.

Japan is one of the world's most seismically active nations - in September 2014, 63 people were killed in a sudden eruption of Mount Ontake.
