ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey

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
There has been no significant change in the seismicity at Pavlof in the past 24 hours. Seismic tremor continues, but at lower amplitudes than previously. For the first time since May 27, no elevated surface temperatures were detected in satellite images during the past 24 hours. No plumes were visible in satellite images, and web camera images show cloudy conditions.
Although activity at Pavlof has declined, eruptive activity could increase again 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 intracaldera cinder cone consistent with continued effusion of lava. No plumes have been observed in satellite images nor reported by pilots or local observers. 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
Low-level clouds obscured the volcano in web camera the past 24 hours. 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.
