What the record says

NCEI’s account, from the sources it cites.

Reporters were allowed to inch closer to the Nakadake peak of Mount Aso on Feb. 8 [2017] after the alert level was lowered to 1 the day before. The media were allowed within a kilometer of the No. 1 crater of the peak, which erupted in October 2016. The eruption, the most violent in 36 years, sent a towering plume of smoke and ash into the sky. After the eruption in October, a station building for a ropeway was half-buried in a vast amount of ash and its roof destroyed. (reference #11756)

Weekly Report 12 October 18 October 2016: Japan Meteorological Agency (JMA) reported that no further explosions were detected after the 7-8 October eruption at Asosan’s Nakadake Crater; white plumes rose as high as 400 m above the crater rim during 11-17 October. The Alert Level remained at 3 (on a scale of 1-5). (reference #2432)
