52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Satellite and web-camera views of Cleveland have been mostly obscured by clouds for the past 24 hours. We have received no other reports of activity.
Sudden explosions of blocks and ash are still possible with little or no warning. 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. Cleveland volcano does not have a local seismic network and is monitored using only distant seismic and infrasound instruments and satellite data.PAVLOF VOLCANO
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Ash emissions from Pavlof continue. Seismic tremor and explosion signals accompany the renewed eruptive activity, which began June 4. Overnight satellite images showed elevated surface temperatures near the volcano's vent, consistent with lava effusion and fountaining.
A satellite image from this morning shows an ash cloud extending roughly 45 km (28 miles) to the southwest, consistent with low level winds. Pilot reports from this morning estimate the cloud to be between 14,000 and 18,000 ft asl.
