Mt. Spurr, one of North America’s more active volcanoes, is closely being watched due to increased geological disturbances and activity. The most recent eruptions from the southern vent of Spurr volcano (Crater Peak) occurred in June, August, and September 1992. In the June eruption, winds carried the ash as far as Denali Park. According to the Alaska Volcano Observatory, in August, Anchorage received 3 mm of ash, shutting down Ted Stevens International Airport for 20 hours, and in September, ashfall impacted populations in the MatSu region.
Recent developments indicate a potential Mt. Spurr eruption in Alaska, so faculty, staff, and students in or near potential ashfall zones must be prepared. While an eruption remains uncertain, the State of Alaska and agency partners believe it could occur within weeks to months.
Now is the time to take proactive steps to prepare at work, school, and home. UAF Emergency Management, along with the help of partner agencies, has put together some information to help you prepare and safeguard yourself and mitigate the potential impacts of volcanic ashfall in your local area. This information, along with any updates regarding Mt. Spurr, can be found on UAF on Alert.
In addition to updates from UAF Emergency Management, UAF staff, faculty, and students can access additional resources to prepare for and respond to a volcanic eruption. The links below provide up-to-date information on Mt. Spurr’s activity to keep Alaskan communities informed.
