Dark areas spotted on Saunders and Bristol islands

Satellite image of Saunders Island on the 12th March 2017 shows a dark spot on the summit area of Mount Michael indicating that some sort of activity has occurred, probably an eruption or perhaps some increased fumarolic activity. No thermal anomaly however was detected. The dark spot on Mount Michael was also slightly visible in satellite imagery. In the following days, cloud cover obscured views.

In the satellite image of a partially visible Bristol Island on the 17th March 2017, a tip of a lava flow is visible at the northern part of the island. Did a new eruption recently occur or has the heat from the potentially still hot lava flow of last year's eruption melted the surface snow? No recent thermal anomaly was detected.

Possible ash emission on Zavodovski

Satellite image from 18th January 2017 shows a plume being emitted from Mount Curry Volcano on Zavodovski Island. In my opinion, the plume appears to have some possible ash content and it's possible an eruption might've occurred.
