Two plumes in the South Sandwich Islands

In the satellite images from the 4th December 2017 two plumes are present originating from Zavodovski Island and Saunders Island respectively. On Zavodovski Island a whitish plume is seen drifting northeast originating from Mount Curry, and on Saunders Island a dirty white to light grey plume originating from Mount Michael is seen drifting east-northeast to northeast. In my view the plume from Mount Curry is most likely to be a gas plume but I wouldn't rule out the possibility of some slight ash content, and the plume from Mount Michael may have some possible ash content.
