Gareloi (United States, Aleutian Islands): A single brief explosion was detected in geophysical data at 07:27 AM AKDT (15:27 UTC), the Alaska Volcano Observatory reported.
As a result, AVO is raising the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY. It is unknown if a volcanic ash cloud was produced as cloud cover up to about 20,000 feet above sea level is obscuring the volcano.
If an ash cloud were produced, the amount of ash would be minor due to the short duration (less than 1 min) of the explosion. Infrasound data indicates the explosion likely occurred from the south crater of Mount Gareloi.
Fuego (Guatemala): Intermittent volcanic ash emissions from Fuego were observed by webcam but not detected by satellite due to heavy meteorological cloud cover as of October 1, 2026, 16:30 UTC. Forecasts indicate possible ash movement towards the east-northeast through the next 18 hours.
