Possible eruption on Mount Curry

A light grey plume is seen drifting in a northerly direction in the satellite image from 13th July 2017 originating from Mount Curry Volcano on the northern side of Zavodovski Island. As this plume looks like it is coming from the crater area of Mount Curry, I am under the opinion that there's a good chance that this could be an ash plume indicating that an eruption took place.

Emissions from Saunders Island

Satellite image from 5th June 2017 shows a white plume originating from Saunders Island drifting south. The plume also appears in an image from 9th June drifting west-southwest and again on 10th June drifting west. The likelihood is that it's more likely to be a gas or vapour emission. No thermal anomaly was detected at around that time.
