AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Sunday, July 12, 2009, 1:17 PM AKDT (Sunday, July 12, 2009, 21:17 UTC)


REDOUBT VOLCANO (VNUM #313030)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

No significant changes have been observed at Redoubt Volcano over the past 24 hours. Seismicity remains low, and webcam views show continued steaming from the lava dome. The fresh, hot lava dome remains potentially unstable, and its collapse would likely result in significant ash production, hot block and ash flows, and flooding in the Drift River valley. AVO continues to closely monitor Redoubt's activity.



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

Satellite images continue to show a thermal anomaly at Shishaldin. Seismic, deformation, and gas emission data do not show anything abnormal at the volcano, and there is currently no indication that an eruption will occur. AVO will continue to carefully monitor activity at Shishaldin.


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

AVO has observed no further activity at Cleveland since the small eruption on June 25. Clouds have obscured views of the volcano in satellite and web camera images over the past 24 hours.
