55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption at Pavlov volcano is on going. Seismic tremor continues to be detected in seismic data. Current weather conditions prevent clear views of the volcano in satellite images. The volcano has been obscured by weather in recent web camera images.

Previous eruptions of Pavlof Volcano have lasted for weeks, months or years and often exhibit fluctuating levels of activity and it is not uncommon for the volcano to enter short periods of repose followed by vigorous ash emissions, lava fountaining, and lahar generation. Occasionally past eruptions have generated vigorous ash emissions and clouds that reached 30,000-50,000 ft. above sea level. We expect this eruption to proceed in a manner similar to previous eruptions.

Eruptive activity at Pavlof could increase with little to no warning.

56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

The eruption of Veniaminof volcano continues. Volcanic tremor continues to be detected in seismic data. Recent satellite images show cloudy weather conditions that prevent clear views of the volcano. Views of the volcano from the web camera have been obscured by weather as well. Small, short lived ash emissions may be occurring that may not be detected in satellite data.

Recent eruptions of Veniaminof volcano have all occurred from vents located on the cinder cone inside the caldera and were characterized by brief bursts of ash emission and small explosions with ash fall limited to areas on the flanks of the volcano. While a larger ash emission is not expected, it is possible and should be detected on the current seismic network. The current lava flow is expected to remain within the confines of the caldera. There is a possibility that activity at the volcano could increase with little to no warning.

52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

No elevated surface temperatures were observed in satellite images. We have received no other reports of activity at the volcano.

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.
