Some flights to Western Alaska canceled due to Kamchatka eruption
The eruption of a volcano this week on Russia’s Russia’s Kamchatka Peninsula has prompted some Western Alaska flight cancellations.
Monday noticed Shiveluch Volcano’s largest eruption in almost 60 years with ash exploding at the least 50,000 ft into the air. Whereas the majority of that cloud is to the southwest of Alaska across the western Aleutians, a ribbon of volcanic fuel and a bit ash reached the mainland on Wednesday.
Alaska Airways spokesperson Tim Thompson mentioned in an e-mail that as a security precaution the corporate canceled eight flights between Western Alaska airports and Anchorage on Wednesday. These flights have been to Adak, Bethel, Dillingham and King Salmon. Thompson mentioned they’re monitoring the cloud and will should cancel extra flights within the coming days, with a Twitter publish from the airline Thursday morning recommending passengers examine their flight standing.
The Nationwide Climate Service additionally issued an aviation warning for the Aleutians.
Dave Schneider, a analysis geophysicist with the Alaska Volcano Observatory in Anchorage, says lava from the Shiveluch volcano types a dome, components of which periodically collapse and create ash clouds.

“What occurred a pair days in the past was far more vital,” he mentioned. “It’s nonetheless too early to essentially know precisely what went on, however I surmise that a big a part of the lava dome that’s been rising for years collapsed and unleashed a reasonably good sized eruption.”
The large cloud was initially shifting west, blanketing villages in Russia with a thick layer of ash. However as one other climate system got here in, it began shifting east, towards Alaska. And components of the cloud are peeling off.
“Presently, the ash remains to be out within the western Aleutians,” Schneider mentioned. “However as bits and items of it are kind of getting pulled off, kind of such as you’re making toffee, and you may pull a department off, and it’ll kind of go off in its personal route.”
One cloud really handed over Dillingham on Wednesday, Schneider mentioned, although it was primarily sulfur dioxide fuel and contained little or no ash.
“Each of these are a part of the volcanic cloud that was produced,” he mentioned. “And with satellites, we’re capable of observe these and that helps the climate service difficulty forecasts and kind of see the place the cloud is and the place it’s shifting.”
The volcano’s emissions decreased on Wednesday, and Schneider mentioned that whereas there’s no guaranteeing precisely when the cloud will disperse, that’s a good signal that journey may quickly be again to regular.
