Extensive gas plume from Saunders Island

Satellite image from the 10th October 2019 shows an extensive white plume being emitted from Michael Volcano on Saunders Island and being blown in an east-southeasterly direction. There is no thermal anomaly present in the summit crater area which brings me to the opinion that it is just a gas plume.

Further images of Saunders Island from the 13th and 15th October 2019 show nothing more than degassing activity on Michael Volcano.

Few more photos of the South Sandwich Islands volcanoes

Some of you may or may not recall a post I done earlier this year showing photos of the South Sandwich Islands volcanoes taken by a scientist on board the Discovery Expedition 99 voyage to South Georgia Island and the South Sandwich Islands.

Well this is a kind of belated post but another scientist, Chris Darby who was also aboard the same expedition that time had also gave me kind permission to share his pics.

All photos taken by Chris Darby, late February to early March 2019.

Quick Mt. Michael September satellite image updates

This is just a quick post so I'm able to catch up quicker, but below are some satellite images of activity on Mount Michael during September taken from the Sentinel-hub website. It's mostly about the plumes but one image shows a weak thermal anomaly inside the summit crater.
