Aira volcano (Kyushu, Japan) - Smithsonian / USGS Weekly Volcanic Activity Report for 16 November-22 November 2022 (Continuing Activity)

JMA reported ongoing eruptive activity at Minamidake Crater (at Aira Caldera's Sakurajima volcano) and nighttime crater incandescence during 14-21 November. Sulfur dioxide emissions were slightly high on 14 November at 1,100 tons per day. Six eruptive events and four explosions (during 15-16 and 20-21 November) produced volcanic plumes that rose as high as 2.2 km above the crater rim and ejected large blocks as far as 900 m from the vent.
The Alert Level remained at 3 (on a 5-level scale), and residents were warned to stay 2 km away from the crater.
