#Shishaldin RED/WARNING
Fri, Sept 15, 2023, 5:41 PM AKDT

Ash is currently being produced and is drifting to the east below the cloud deck of 27,000 ft above sea level. The Aviation Color Code and Volcano Alert Level is being raised to RED/WARNING. Recent significant ash events during the current eruption resulted in ash clouds with heights up to 40,000 ft (12 km) above sea level. These events can occur with little warning. It is also possible that ash emissions may occur at a lower-level, steady state and be sustained for many hours. AVO is monitoring the volcano closely and will issue additional Volcanic Activity Notices to provide notice of significant changes in activity as they occur. Shishaldin activity page:
