Eruptive activity on Michael Volcano possibly ended in April

While studying recent satellite images of Saunders Island on Sentinel Hub, I discovered that the last time a thermal anomaly was present inside the crater of Mount Michael was on the 3rd April 2018. White plumes continued to be present in images until the 18th April 2018.

The thermal anomaly on Mount Michael started appearing in satellite images on the 31st January 2018 but was last seen on the 3rd April 2018. In my opinion this suggests that some kind of eruptive activity was going on in that period either at the most, a temporary lava lake or at the least, some intensive strombolian activity.
