Volcanic ash originating from Russia’s Kamchatka Peninsula canceled Alaska Airlines flights to Nome and Kotzebue Tuesday morning.
The ash plume came from the Klyuchevskoy volcano, prompting an advisory from the Alaska Volcanic Ash Advisory Center.

Volcanic ash is a silent killer, more so than lava: What Alaska needs to know with Mount Spurr likely to erupt
When volcanoes like Alaska’s Mount Spurr erupt, the ash can damage people’s lungs, smother crops and kill animals, and the harm can continue to spread long afterward.
