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 partially clear web camera views from this morning show vigorous steaming from the lava dome. No ash signals have been observed in radar or satellite data. The hot, 2009 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.
