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. Consistently elevated temperatures at the summit of Shishaldin Volcano were recorded in satellite images today. No significant seismicity was noted. Low-level steam emissions were observed in clear web camera images today.
SEMISOPOCHNOI VOLCANO
(VNUM #311060)
51°55'44" N 179°35'52" E,
Summit Elevation 2625 ft (800 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code:
YELLOW
The Semispochnoi earthquake swarm that began on June 9 continues. Clouds obscured views of the volcano by satellite today and AVO has received no reports from pilots or mariners of any unusual activity at Semisopochnoi.
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
Weakly elevated temperatures in the vicinity of the newly erupted lava flows on the northwest flank were recorded in satellite images today. Small, discrete seismic events continue. Eruptive activity could resume at any time with little or no warning.
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 significant activity was observed in mostly cloudy satellite images 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
Weak elevated surface temperatures consistent with cooling lava flows were observed satellite images today. Seismicity remains slightly above background. No activity was observed in clear web camera views.
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.
