The recent volcanic activity the past few days at St. Augustine Volcano has yet to affect Ted Stevens Anchorage International Airport directly with ashfall, but a number of flights in and out have been diverted or cancelled, as wind trajectories can easily take volcanic ash north and eastward into the Anchorage area. Winds are forecast to blow north to east over the next few days.
According to KTUU (Anchorage) TV news reports, schools in Homer, Alaska were closed Friday when a light dusting of ash fell on the town.
St. Augustine Volcano dominates its eponymous uninhabited sixty-square mile island at the mouth of Cook Inlet...the bay that leads about 150 miles inland to the city of Anchorage. On Friday the 13th, the 4,134-foot conical mountain had five explosive series of eruptions, sending ash over 20,000 feet into the sky. The western shore of Cook Inlet hosts a handful of larger volcanoes that are closer to Anchorage and have been known every few years or so to spout ash that disrupts air travel in the region.
