What does this data set describe?

Title: Recently active volcanoes of Alaska
Abstract:
Recently active volcanoes of Alaska, Miscellaneous Publication 133 v. 6, 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 a 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 approximately 10 degrees C of the boiling point, OR 4) Significant, measured, volcanic-related, non-eruptive deformation, OR 5) Documented earthquake swarm with strongly suspected volcanic cause. This data is released as a Miscellaneous Publication with an open end-user license. The data are available from the DGGS website: http://doi.org/10.14509/31086.

Why was the data set created?

The purpose of this dataset is to document the location and most recent eruptive events of the historically active volcanoes throughout Alaska.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2023 (process 1 of 1)
    Data compilation - The volcano names, date of last eruptive event, and location information in this dataset comes from the AVO website, www.avo.alaska.edu, accessed in January 2020. The volcano information on the AVO website is contained within a database and was compiled almost exclusively by Cheryl Cameron. 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. AVO website and database is extensively reviewed by Alaska Volcano Observatory staff and work to implement updates and corrections is ongoing. 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 volcanoes listed meet at least one of the following criteria since 1700 CE: 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 a 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 approximately 10 degrees C of the boiling point, OR 4) Significant, measured, volcanic-related, non-eruptive deformation, OR 5) Documented earthquake swarm with strongly suspected volcanic cause.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The volcano names, date of last eruptive event, and location information in this dataset comes from the AVO website, www.avo.alaska.edu, accessed in January 2023. 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.
  2. How accurate are the geographic locations?
    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.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This data releaase is complete. 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 a 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 approximately 10 degrees C of the boiling point, OR 4) Significant, measured, volcanic-related, non-eruptive deformation, OR 5) Documented earthquake swarm with strongly suspected volcanic cause.
  5. How consistent are the relationships among the observations, including topology?
