summary:

AVO is once again receiving ground-based monitoring data for five volcanoes in the Adak area. The data had been unavailable since January 2 due to a storm-related power failure at our telecommunication link in Adak. Power was restored on January 28, and as a result realtime data flow has been restored. AVO can once again seismically monitor these volcanoes, assess volcanic unrest, and quickly confirm or dismiss reports of activity. 

For Tanaga, Takawangha, and Gareloi, which were previously at UNASSIGNED due to the outage, we are changing the Aviation Color Code and Volcano Alert Level to GREEN/NORMAL. 

Great Sitkin and Kanaga remain at ORANGE/WATCH and YELLOW/ADVISORY, respectively.
