Online_Linkage: http://dx.doi.org/10.14509/20181 Description: Abstract: This data lists the historically active volcanoes of Alaska and the year of the last major eruptive event. The 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 degrees 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. Purpose: The purpose of this dataset is to document the location and most recent eruptive events of the historically active volcanoes of Alaska. Supplemental_Information: The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships and correspond to subdirectories within the data distribution package. The metadata layer provides the metadata, project border files, or other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section.

The volcano information on the AVO website is contained within a database and was compiled almost exclusively by Cheryl Cameron, and reviewed by staff of the Alaska Volcano Observatory. This database contains information on all published reports about Quaternary and younger Alaskan volcanism. The volcano names, locations, and eruptive history information found in the database is compiled by studying all locatable published documents. All of the locations were entered into the database, plotted in a GIS, and visually checked for accuracy. Where all published locations were inaccurate, new locations were generated by plotting a point within the GIS using a USGS digital topographic map. Logical_Consistency_Report: Not applicable Completeness_Report: This data provides the locations of historically active volcanoes of Alaska 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 degrees 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. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location values were compiled from existing published resources and plotted using a GIS to visually verify accuracy. Where published locations of volcanic features appeared inaccurate, new locations were generated by creating a point on USGS digital topographic maps (using the largest scale available, 1:63,000 or 1:250,000) within the GIS.

The volcano information on the AVO website is contained within a database and was compiled almost exclusively by Cheryl Cameron, and reviewed by staff of the Alaska Volcano Observatory. This database contains information on all published reports about Quaternary and younger Alaskan volcanism. The volcano names, locations, and eruptive history information found in the database is compiled by studying all locatable published documents. All of the locations were entered into the database, plotted in a GIS, and visually checked for accuracy. Where all published locations were inaccurate, new locations were generated by plotting a point within the GIS using a USGS digital topographic map. Although the database contains information on all volcanic features in Alaska with activity within the last two million years, the list given in this publication is for "historically active" volcanoes. To be considered "historically active" 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 degrees C of the boiling point, or (4) significant, measured, volcanic-related, non-eruptive deformation, (5) documented earthquake swarm with strongly suspected volcanic cause. To create this list, all references and volcanoes were reviewed to determine whether or not a volcano was eligible. Eruption history information was compiled from all locatable sources, and then reviewed by AVO staff for reliability, consistency, and accuracy. The eruption history information contained in the database was distilled here to the year of the last known major eruption, defined here as an eruption of juvenile tephra to at least several thousand meters above the vent, or an eruption forming a lava flow or dome. Many of these volcanoes have had more recent eruptions that do not meet this criteria (e.g. Fourpeaked had a phreatic explosion in 2006).
