52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
No additional activity has been detected at Cleveland Volcano in the last 24 hours.
It remains possible for sudden explosions of ash to occur at any time. Ash clouds exceeding 20,000 feet above sea level may develop. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours. If a large, explosive, ash-producing event occurs, seismic, infrasound, or volcanic lightning may be detected by local and regional monitoring networks. There is no real-time seismic monitoring network on Mount Cleveland. ILIAMNA VOLCANO
60°1'55" N 153°5'30" W, Summit Elevation 10016 ft (3053 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Seismic activity at Iliamna Volcano remains above background. This activity does not mean that an eruption is imminent or certain. A similar seismic swarm in 1996/1997 that was likely related to an intrusion of magma at depth did not culminate in an eruption.
