The Japan Meteorological Agency stated that Mt. Aso erupted at 9:43 am on 14Sep2015. Following the eruption, the Agency raised Mt. Aso’s volcanic alert level from 2 (Do not approach the crater) to 3 (Do not approach to the volcano). The eruption shot volcanic ash 2,000 meters into the air.
The local government is controlling entry to the area within a 4-kilometer of the crater.
(This news was shown to the press on Sep 14. Mt. Aso is one of ‘Hyakumeizan (hundred famous mountains in Japan)’ and, therefore, is very popular for Japanese hikers.)
