Roundup of Global Volcanic Activity - New Activity for the week 21 December - 27 December 2022

Etna - Sicily (Italy) : INGV reported that the vents at the NE base of Etna’s SE Crater, in the Valle del Leone at about 2,800 m elevation, continued to feed lava flows during 19-25 December. The active flow field consisted of overlapping lava flows that expanded into the Valle del Leone and the Valle del Bove. By 25 December the most active lava flow had descended to 2,150 m elevation. Gas emissions rose from the summit craters.

Kaitoku Seamount - Volcano Islands (Japan) : After JMA first reported new activity around the Kaitoku Seamount in August, discolored water continued to be periodically visible in Sentinel satellite images through 27 December. Though weather clouds sometimes prevented views of the vent area, and on occasion no activity was visible in clear images, plumes of discolored water drifting away from the vent area appeared to become more frequent in October. Images from 18 October, and 22 and 27 November possibly captured material at the surface or an eruption plume rising above the water. The Japan Coast Guard posted pictures of disturbed water around the vent in November. Recent Sentinel images on 17 and 27 December captured plumes of discolored water drifting as far as 10 km from the vent area.
