The eruption of the Augustine Volcano has caused disruption for flights in and out of Alaska between Anchorage and Fairbanks. The ash plume makes it difficult to fly, and very dangerous to fly at night.

Alaska Airlines canceled 28 flights on Friday, a major cargo carrier diverted flights from Anchorage to Fairbanks and the Alaska National Guard moved several aircraft out of the city Friday as Augustine Volcano sent ash plumes miles into the sky.

State and city emergency services responders activated operations centers and planned to monitor the volcano’s activity over the long holiday weekend. Several government agencies urged employees to shut down their computers and cover them before leaving their offices. Via Anchorage Daily News
