On October 19, AVO raised the Aviation Color Code and Volcanic Alert Level at Pavlof to YELLOW/ADVISORY. From the Volcano Observatory Notice for Aviation: "Small explosion signals from Pavlof have been detected on the infrasound network located at Sand Point and on the local seismic network today. The volcano is currently obscured by clouds in satellite images. It is unknown if the explosions produced any volcanic ash, but their small size suggests any hazard is currently confined to the area around the volcano's summit. Because these signals are above normal background for Pavlof, the Alaska Volcano Observatory is raising the Aviation Color Code to YELLOW and the Alert Level to ADVISORY." On November 6, 2019, AVO lowered the Aviation Color Code and Volcano Alert Level to GREEN/NORMAL, citing no additional signs of unrest after the explosion signals on October 19.
