Heard volcano (Kerguelen Plateau) - Smithsonian / USGS Weekly Volcanic Activity Report for 24 November-30 November 2021 (Continuing Activity)
Thermal satellite images of Heard Island's Big Ben volcano showed thermal anomalies of varying intensity over the summit area or on the NW and W flanks on 4, 11, 14, and 21 November. Weather clouds prevented views of the volcano on eight other acquisitions during the month. On 11 November four anomalies on the NW flank formed a “v” shape open to the NW, possibly indicating a branched lava flow.
