Thermal anomaly persists on Mount Michael

The thermal anomaly is still present inside the summit crater of Mount Michael on Saunders Island as seen in the recent satellite images from 10th February 2018. As the images were viewed on the EOSDA website, I was able to zoom in on to the summit area of Mount Michael Volcano where I had a more clearer view of the summit crater area.

A degassing plume was present but an infrared image revealed that a thermal anomaly was present in the northern part of the crater interior indicating volcanic activity. It could either be low level strombolian activity, or it could be lava flows covering a small part of the crater interior, or it could be a lava lake.

Thermal anomaly detected on Mount Michael

In a satellite image by Landsat 8 taken on the 31st January 2018, a thermal anomaly is present inside the summit crater of Mount Michael on Saunders Island. It is clearly an indicator that some elevated activity has been taking place inside the crater of Mount Michael.

In my opinion, I believe some low level strombolian activity has been occurring or at least a lava pool is present on the crater floor.
