52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
The low-level eruption of Cleveland Volcano continues. Two small explosions were detected by distant infrasound and seismic networks in the past 30 hours. Weather conditions have been mostly cloudy in the area of the volcano. No ash has been detected or reported.
While the volcano is active, sudden explosions of blocks and ash remain likely. It is possible for associated ash clouds to exceed 20,000 feet above sea level. If a larger ash-producing event occurs, seismic, infrasound, or volcanic lightning networks should detect the event and alert AVO staff. There is no real-time seismic monitoring network on Mount Cleveland 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 remains slightly above background. Nothing unusual was observed in web camera and mostly cloudy satellite images over the past 24 hours.
The current activity at Iliamna does not indicate an imminent or certain eruption. A similar seismic swarm at Iliamna in 1996-1997 was not followed by eruptive activity. Prior to an eruption, AVO would expect to see a further increase in earthquake activity.
