Thermal anomaly present again on Saunders

While studying recent satellite images of Saunders Island on Sentinel Hub, I observed that a thermal anomaly had returned inside the summit crater of Mount Michael on the 23rd September 2018. This indicates that volcanic activity has resumed.

Judging by the size of the double anomaly I am under the opinion that it could either be a lava pond or some mild strombolian activity at the most, or simply some intensive fumarolic activity at the least.
