The volcano had a small eruption from the Nakadake crater today. On the following webcam video for the past 30 hours, a strong increase in activity can be noted during the past 12 hours. The degassing plume possibly contains some ash and faint red glow is visible on some images of tonight (towards the end of the video):

VAAC Tokyo confirms a small ash plume that drifted south at approx 2000 m altitude. A small thermal anomaly is identifiable on satellite data as well.
