Shishaldin Volcano ash clouds disrupts air travel to the Aleutians
Updated 8/15/23 at 7:00 p.m.
Two ash eruptions at Shishaldin Volcano disrupted air travel to the Aleutians Tuesday. A Dutch Harbor airport representative said a Ravn Alaska afternoon flight was canceled from Anchorage to Unalaska and two Aleutian Airways flights were affected: one morning flight to the island was delayed by 30 minutes and an afternoon flight from Anchorage to King Salmon was rerouted back to Anchorage.
The first eruption around 3:35 a.m. released a 35,000-foot ash cloud that slowly drifted northeast into the Bering Sea toward Western Interior Alaska, according to the National Weather Service. The second eruption released a 16,000-foot plume just after 3 p.m.
Shishaldin — located on Unimak in the Eastern Aleutians — is one of the most active volcanoes in the island chain.
There have been several events at the volcano since this eruption began on July 12.
Chris Waythomas, a geologist for the Alaska Volcano Observatory, said experts don't know how long the eruption will last. Previous eruptions at Shishaldin have gone on for months.
