CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Clouds have mostly obscured the summit of Cleveland during the past 24 hours. An AVO scientist on a commercial flight to Adak that passed about 20 mi north of Cleveland Volcano late on the afternoon of August 14 observed that most of the volcano was obscured by clouds blowing in from the Pacific side of the island, but the NW quarter was visible. The volcano was emitting small white "popcorn" puffs of steam ascending to about 100-200 ft above the summit. No other activity of note was observed.


Without a real-time seismic network on the volcano, AVO is unable to track local earthquake activity related to volcanic unrest, provide forecasts of eruptive activity, or confirmation of explosive, ash-producing events. AVO is monitoring the volcano using satellite data as it becomes available.
