ALASKA VOLCANO OBSERVATORY DAILY UPDATE

PAVLOF VOLCANO (VNUM #312030)
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 with slightly higher amplitudes from yesterday. Elevated surface temperatures consistent with lava effusion were detected in satellite images. A small ash plume from the summit vent is also seen in satellite data. Web camera images show mostly cloudy conditions.

Eruptive activity at Pavlof could increase with little warning.



VENIAMINOF VOLCANO (VNUM #312070)
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. Recent satellite images show very high elevated surface temperatures at the intra-caldera cinder cone consistent with continued effusion of lava. No plumes have been observed in satellite images. Volcanic tremor continues unchanged in the past 24 hours. FAA web camera images have been obscured by clouds.








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

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.
