Beside that, strombolian eruptions and spattering continue to take place at Stromboli itself spewing ash plumes from the Central-South crater area.
The behavior of the volcano is mainly characterized by on-off small short-term lava outputs over the past two months or so. Such events are nothing unusual on the volcano.

Weakly elevated surface temperatures and minor "venting" continue to be identified within the active vent, related to the cooling of the recent lava flow.
Therefore, a decision has been made by the Alaska Volcano Observatory to lower the Volcanic Alert Level to "Green".
