Publication_Date: 1998 Title: Volcanoes of Alaska Geospatial_Data_Presentation_Form: map, vector digital data Series_Information: Series_Name: Information Circular Issue_Identification: IC 38 ed. 1998 Publication_Information: Publication_Place: Fairbanks, Alaska - USA Publisher: State of Alaska, Division of Geological and Geophysical Surveys Online_Linkage: http://dx.doi.org/10.14509/7043 Description: Abstract: This dataset comprises the locations of volcanoes and volcanic centers in Alaska. Purpose: The Alaska Volcano Observatory (AVO) is a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of Alaska Division of Geological & Geophysical Surveys (DGGS). AVO monitors and studies Alaska's hazardous volcanoes, predicts and records eruptive activity, and works closely with other agencies to implement public safety measures.

Data_Set_Credit: This research was partially supported by the U.S. Geological Survey (USGS), Department of the Interior, under USGS award number 1434-HQ-96-GR-02713. Additional Acknowledgments: Geology modified from Schmoll and Dobrovolny (1972). Digital cartography by R.A. Combellick and S.M. Weems, with suggestions by A.L. Schell. R.D. Reger and P.J. Haeussler provided helpful comments on the draft map and cross sections. Native_Data_Set_Environment: Microsoft Windows XP SP2, ArcGIS 9.+, and any text editor. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The "ak_volccent" data was created by digitizing points from a paper copy of U.S. Geological Survey Map I-1091-F, showing distributions, composition and age of late Cenozoic volcanic centers in Alaska. Coverages were created using Arc/Info 7.0.4, distributed by ESRI, Inc. Locations of volcanoes were acquired from latitude and longitude points found in Luedke and Smith (1990) and Wood and Kienle (1990), although errors may exist. The points were entered into a spreadsheet and e00 coverages were created using GIS software. The structural lines on the map may have been digitized into a GIS environment using data from Plafker and others (1994) and Moore (1992), or an unknown source. Logical_Consistency_Report: Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships. Completeness_Report: This data set includes locations of volcanoes and volcanic centers in Alaska as of 1998. The elevation, morphology, age, type of eruption, and number of eruptions was gathered in July 1997. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Luedke, R.G.

Process_Step: Process_Description: The "akvolcanoes" data was created from a file of volcano names and locations from the Alaska Earthquake Information Center. The details on each volcano were obtained from AVO research and the publication, Volcanoes of North America-United States and Canada (Wood and Kienle, 1990). The "ak_volccent" data was created by digitizing points from a paper copy of U.S. Geological Survey Map I-1091-F, showing distributions, composition and age of late Cenozoic volcanic centers in Alaska. Coverages were created using Arc/Info 7.0.4, distributed by ESRI, Inc. Locations of volcanoes were acquired from latitude and longitude points found in Luedke and Smith (1986) and Wood and Kienle (1990), although errors may exist. The points were entered into a spreadsheet and e00 coverages were created using GIS software. The structural lines on the map may have been digitized into a GIS environment using data from Plafker and others (1994) and Moore (1992), or an unknown source. Polygons depicting the outcrop areas of volcanic rocks were generated from Luedke and Smith (1986). Factual information regarding volcanoes was produced in part from Myers and others (1997) and Wood and Kienle (1990).
