52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Nothing unusual was observed in mostly cloudy satellite data of Cleveland Volcano over the past 24 hours. No ash emissions or other signs of unrest were detected or reported.
While Cleveland Volcano is active, sudden ash-producing explosions may occur at any time. Ash clouds associated with explosive events could extend to more than 20,000 feet above sea level. If a large ash-producing eruption occurs, seismic, infrasound, or volcanic lightning networks should detect the event and alert AVO staff. There is no real-time seismic monitoring network on Cleveland Volcano so AVO is unable to track activity in real time.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 has remained slightly above background over the past 24 hours. AVO has received no reports of unusual activity at the volcano.
The current level of activity at Iliamna does not indicate an imminent or certain eruption and seismic activity appears to be declining gradually. A similar seismic swarm occurred at Iliamna Volcano in 1996-1997 and was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a significant increase in earthquake activity beneath the volcano.
