Redoubt volcano teased air travelers Friday afternoon after a string of eruptions the previous night and morning, calming just long enough to get airlines flying again only to erupt once more at 5:35 p.m. Two more eruptions followed, 7:25 p.m. and 11:20 p.m.
It's a vexing pattern that scientists from the Alaska Volcano Observatory said is likely to continue for several months, based on the record of the volcano's last eruption cycle nearly 20 years ago.
The active volcano, one of four in the Cook Inlet area, is about 100 miles southwest of Anchorage and directly across the Inlet from Kenai, situated in a location where it can disrupt flights to and from Anchorage when belching ash.
The observatory reported that the first afternoon eruption sent ash rising to 40,000 feet based on radar observations from the National Weather Service. The second shot ash to 51,000 feet. The third sent ash 40,000 feet.
