Cameron, C.E. 2005 vector digital data Raw Data File RDF 2005-3 Fairbanks, AK State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys http://dx.doi.org/10.14509/7103 This publication provides digital point data for the locations of 127 volcanic centers in Alaska younger than 2 million years. Information about whether a volcano has been historically active is also provided. Detailed information about each center can be found on the Alaska Volcano Observatory website at http://www.avo.alaska.edu To provide an authoritative file of volcano locations The volcano locations in this file were compiled from existing publications whenever possible, and from USGS topographic maps when published locations could not be found. In the case of more than one published location for a volcano, additional maps of the volcano, as well as people who have expert knowledge of the volcano, were consulted. The layers listed below are present as ArcGIS shape files. Attribute information for the following layers (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each layer is listed and described in detail under its own heading starting "Entity_Type_Label." Layers include: >AKvolclatlong latitudes and longitudes of volcanoes 200502 publication date Complete Irregular -178.793900 179.831680 67.300000 51.790300 ISO 19115 Topic Category geoscientificInformation none Active Volcanoes Volcanoes none Akutan Amchixtam Chaxsxii Atka Basalt of Gertrude Creek Black Peak Buzzard Creek Cone 3110 Cone 3601 Devils Desk Double Glacier Douglas Duncan Canal Dutton Emmons Lake Espenberg Folsoms Bluff Gordon Iliamna Imuruk Lake Ingakslugwat Hills Iron Trig Cone Kaguyak Knob 1000 Kochilagok Hill Kookooligit Mountains Kukak Kupreanof Makushin Martin Nelson Island Novarupta Nunivak Island Pavlof Pavlof Sister Porcupine Prindle Volcano Rainbow River Cone Skookum Creek Tanada Peak Teller Basalt Field Togiak Volcanics Unnamed 1 (near Kupreanof) Unnamed 2 (near Ukinrek Maars) Volcano 1 near Kupreanof Volcano 2 near Kupreanof Volcano 4 near Kupreanof Wrangell none Quaternary This data set is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

This dataset was created as part of the Alaska Volcano Observatory's Geological Database of Information on Volcanoes in Alaska (GeoDIVA) project. Microsoft Windows XP SP2, ArcGIS 9.+, and any text editor. The attributes of this geospatial dataset consist of text identifiers and numeric codes that indicate the name, latitude, and longitude of Alaska volcanoes younger than 2 million years. Volcanoes that have been active during historic time (as described in Miller and others, 1998, Catalog of Historically Active Volcanoes) are attributed with a "1" in the "Historical" column. To check attribute accuracy, plots of volcano names and locations were visually compared with other Alaska maps and volcano listings. This dataset consists only point data and does not require topology. This dataset includes volcano names of volcanoes in Alaska younger than 2 million years, as compiled in Miller and others (1998), Simkin and Siebert (1994), and Wood and Kienle (1990), as well as additional features located by Alaska Volcano Observatory geologists. In instances where the same feature is known by different names, this dataset attempts to use the most common name. In instances where a volcanic feature contains many smaller volcanic vents (for instance, Pyre Peak is a smaller vent at Seguam volcano), this dataset names only the larger feature. Points were located by compiling previously published data, or in the case of no previously published location, heads-up screen digitization of mapped data using raster images of topographic base maps to an estimated horizontal accuracy of about 1,000 m.
