Between the 27th and 30th August, I noticed what appeared to be a possible plume originating from the Mount Michael volcano on Saunders Island while looking at the EOSDIS website. Because the view was mostly obscured by clouds, it was difficult to determine or verify whether or not it was clearly a plume nor what was going on. If it's a plume then it wasn't easy to tell whether it was an eruption or just a gas plume either. Or it could've simply been a wind current.
