Mount Shinmoedake on the border of Miyazaki and Kagoshima prefectures erupts for the first time in six years on Oct. 11. (Eiji Hori)

Kyushu's Mount Shinmoedake blew its stack for the first time in six years early Oct. 11, sending a plume of ash 300 meters into the air.

The eruption, although minor, followed the Japan Meteorological Agency's decision Oct. 5 to raise the volcano’s activity alert to Level 2, warning climbers to stay away from the crater.

The level was raised again Oct. 11 to Level 3, warning people to stay away from the mountain. It was the first such warning since October 2013 amid fears of a larger eruption that could hurl large cinders two kilometers from the crater.

No flying cinders were evident this time around.

The volcano, part of the Kirishima range in southern Kyushu, straddles the border of Miyazaki and Kagoshima prefectures. It previously erupted Sept. 7, 2011.
