Possibly a lava lake on Mount Michael?

The latest Sentinel-2 images of Saunders Island as viewed on the EOSDA website show that the activity on Mount Michael pretty much remains the same. An infrared false colour image shows that a thermal anomaly still appears inside the summit crater of Mount Michael indicating possible lava lake activity.

Possible eruption on Zavodovski plus activity persists on Saunders Island

Satellite image from 23rd March 2018 shows what appears to be a dirty grey colour on Zavodovski Island with a hazy plume extending southeast of the island for a short distance. This suggests that it's likely to have been an eruption which occurred on Mount Curry.

Meanwhile, down at Saunders Island a satellite image from 29th March 2018 shows a hazy plume extending east-southeast then east. Then again in an image from 3rd April 2018 a hazy plume is seen extending southwest of the island along with an additional white plume which is seen drifting towards the southeast before changing direction to the southwest.

This indicates that the activity on Mount Michael more or less remains unchanged.
