Sheveluch Volcano, located in the Russian Far East on the Kamchatka Peninsula (56.65°N 161.36°E), erupted explosively on April 10 (Alaska date) and produced a large volcanic ash and gas cloud up to ~40,000 feet (12.2 km) above sea level. Over the past several days, the volcanic cloud has drifted eastward over Alaskan air space. Although this cloud poses a potential hazard to aviation and has disrupted some flights, no ashfall is expected on Alaska communities.
Whenever ashfall is expected in Alaska, the Alaska Volcano Observatory works cooperatively with the National Weather Service Anchorage Forecast Office, which issues products to advise the public on the timing and severity of the ashfall. Ashfall information can be found at: https://www.weather.gov/afc/
The airborne cloud is being tracked by the National Weather Service Alaska Aviation Weather Unit and Anchorage Volcanic Ash Advisory Center. The latest warnings for aviation are posted at: https://www.weather.gov/aawu/sigmets.
