CLEVELAND VOLCANO
(VNUM #311240)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code:
YELLOW
Conditions have been partly cloudy to cloudy at the volcano during the past 24 hours. No unusual activity has been reported.
Sudden explosions of blocks and ash remain possible with little or no warning, although the last confirmed explosion occurred on August 20. Ash clouds, if produced, could exceed 20,000 feet above sea level. If a large ash-producing event occurs, nearby seismic, infrasound, or volcanic lightning networks should alert AVO staff quickly. However, for some events, a delay of several hours is possible. There is no real-time seismic monitoring network on Mount Cleveland and AVO is unable to track activity in real time.

60°1'55" N 153°5'30" W,
Summit Elevation 10016 ft (3053 m)
