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 low-level eruption of Pavlof continues. Elevated surface temperatures, seen in satellite imagery, persist at the summit of the volcano which is consistent with lava at the surface. Last night (5/31)weak incandescent glowing at the summit was observed in FAA web camera images located in Cold Bay. Clouds obscured views of the volcano by web camera today. No ash clouds have been detected in satellite imagery. Weak seismic activity is being detected on the Pavlof network. Yesterday small explosion signals were detected by a distant infrasound sensor.

SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Low-level eruptive activity continues at Shishaldin. Satellite images indicate that elevated temperatures persist. Views of the volcano by web camera are obscured by clouds today.

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 activity was observed at Cleveland today. Views of the volcano by web camera and satellite are obscured by clouds today.

VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismicity remains slightly above background. Weakly elevated surface temperatures were observed in satellite imagery today which is consistent with cooling lava.

OTHER ALASKA VOLCANOES

Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/

AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
