Historically active volcanoes of Alaska

Metadata Updated: November 10, 2020

This data lists the historically active volcanoes of Alaska, their location in latitude/longitude decimal degrees, and the year of the last major eruptive event. The 52 volcanoes listed meet at least one of the following criteria since 1700 CE: (1) documented, unquestioned eruption, or (2) a strongly suspected eruption, often an eruption documented in the historical account with very little information (current geologic knowledge must not contradict the eruption account), or (3) persistent (usually on the order of decades, but certainly longer than several months) fumaroles, with temperatures (where measured) within ~10°C of the boiling point, or (4) significant, measured, volcanic-related, non-eruptive deformation, (5) documented earthquake swarm with strongly suspected volcanic cause.For the purposes of this dataset a major eruptive event is considered to be one in which juvenile lava erupt as a lava flow or dome or as an explosive column reaching an altitude of several thousand meters above the vent. This data is represented cartographically in Alaska Division of Geological & Geophysical Surveys Miscellaneous Publication 133 (Schaefer, J.R., Cameron, C.E., and Nye, C.J., 2009) where the volcano locations are displayed on a grayscale digital shaded relief image of Alaska with a background image of colorized bathymetry.
