PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismic data from the Pavlof network has been unavailable for the past day due to technical issues at the receive facility in Cold Bay. This problem is being addressed but it is unclear when data flow will be restored. No elevated surface temperatures or ash emissions observed in mostly cloudy satellite data. Web camera views from Cold Bay obscured by clouds. It remains possible for eruptive activity to resume at any time.

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

Low-level eruptive activity consisting of lava effusion and minor emissions of steam and ash continues. Nearly continuous, gradually fluctuating volcanic tremor and occasional explosions have been observed in seismic data over the past 24 hours. Highly elevated surface temperatures at the intracaldera cone have been observed in satellite data, indicative of the continued eruption of lava. Pilot reports from this morning indicate minor ash emissions, but it is not detectable in satellite data. Please refer to the NWS Alaska Aviation Weather Unit (http://aawu.arh.noaa.gov/sigmets/) for aviation information.





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

Satellite observation and views from the Nikolski web camera have been obscured by clouds and fog over the past day. AVO has received no other reports of activity at the volcano.
