JMA reported that the eruption at Suwanosejima's Ontake Crater continued during 14-21 November and crater incandescence was visible nightly. Eruption plumes generally rose 600 m above the crater rim and blended into weather clouds. An explosion at 0251 on 15 November ejected blocks 500 m from the vent and produced an eruption plume that rose 2.3 km above the crater rim and drifted SE.
The Alert Level remained at 3 (on a 5-level scale), and residents were warned to stay 2 km away from the crater.
