Ash emission on Zavodovski Island

An ash plume originating from Zavodovski Island is visible in a satellite image from 9th December. The ash plume is seen drifting south-southwest but judging from the image it doesn't look like that it's originating from the summit crater of Mount Curry, but from the Asphyxia Plain area of the island. So we could be looking at a possible flank eruption. As the plume is greyish in colour, in my opinion that's what gives it away.
