Information statement on Mount Sheveluch ash disrupting flights in Alaska

Mount Sheveluch, located on Russia's Kamchatka Peninsula, produced ash clouds this week that drifted to Alaska, disrupting flights to both Ted Stevens Anchorage International Airport and Fairbanks International Airport. AVO does not monitor volcanoes on Russia’s Kamchatka Peninsula, but does maintain situational awareness and collaborates closely with National Weather Service on tracking ash clouds from Eastern Russia. The NWS Anchorage Aviation Weather Unit (AAWU) and the Anchorage Volcanic Ash Advisory Center (VAAC) are responsible for tracking ash clouds and issuing aviation warnings for any ash affecting U.S./Alaska airspace, regardless of its origin. The recent Sheveluch activity that affected Alaska airspace has been monitored closely by these agencies. In Alaska, the NWS Center Weather Service Unit is also collocated with the FAA and works closely with AAWU and VAAC during volcanic events.

AVO's David Fee spoke to AK Public Media about the ash clouds originating from Mount Sheveluch this week.
