What does this data set describe?

Title: Active Volcanoes of Kamchatka and the Kurile Islands
Abstract:
This data lists the active volcanoes of Kamchatka and the Kurile Islands, their location in latitude/longitude decimal degrees, and the year of the last major eruptive event. The 65 volcanoes listed meet at least one of the following criteria: (1) an historically documented eruption, (2) fumarolic activity, but without a historically documented eruption, or (3) potentially active volcanoes which have erupted within the past 3500 years.
Supplemental_Information:
The decimal degree locations and the names of the volcanoes in this dataset were taken from the Kamchatka Volcanic Eruption Response Team (KVERT) website, accessed March 15, 2010. This list of "volcanoes" includes volcanic centers, groupings of several related volcanoes, as well as individual vents. Names given here are taken directly from the English-language catalog of active volcanoes of Kamchatka and the Northern Kurile Islands on the KVERT website, and information on the Kurile Island volcanoes provided by Marina Chibisova, Institute of Marine Geology and Geophysics, Yuzhno-Sakhalin (personal communication, 2010). English-language names were reviewed by Olga Girina (KVERT) and Marina Chivisova (SVERT) and corrected for current preferences. The publication consists of a map and a spreadsheet which contains location information.

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 2)
    I obtained the GTOPO30 and ETOPO2 baselayer data from ESRI ArcGIS 9, ESRI Data and Maps 9.3.1, Service Pack 3. This data is available to the public on the internet, from the USGS and NOAA, shown below. GTOPO30 - Available as a download from USGS Earth Resources Observation and Science (EROS) Center: <http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/GTOPO30> <http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/gtopo30_info> ETOPO2 - Available as a download or DVD from the NOAA National Geophysical Data Center <http://www.ngdc.noaa.gov/mgg/fliers/01mgg04.html>

    Date: 2010 (process 2 of 2)
    KVERT is a collaborative project of scientists from the Institute of Volcanology and Seismology (IVS), the Kamchatka Experimental and Methodical Seismological Department (KEMSD), and the Alaska Volcano Observatory. IVS and KEMSD are located in Petropavlosk, Kamchatka peninsula, as part of the Kamchatka Science Center. The volcano information on the KVERT website is presented as a catalog providing the name, IAVCEI catalog #, Lat-Long location, date of the last eruption, and elevation of volcanoes of Kamchatka and the Northern Kurile Islands. The catalog was prepared from reports by KVERT, IVS, and scientific publications. Author and curator of the catalog is Olga Girina, IVS. Metadata for the catalog can be found on-line on the IVS website: <http://www.kscnet.ru/ivs/metadata/index.php?f=show&id=185> (Russian language). To be considered an "Active Volcano" the volcanoes of the KVERT catalog must meet at least one of the following criteria. 1) A historically documented eruption, or 2) a state of fumarolic activity, but without a historically documented eruption, or 3) potentially active volcanoes which have erupted in the past 3500 years (from dating of the last eruption).SVERT (Sakhalin Volcanic Eruption Response Team) holds responsibility for monitoring volcanoes of the central and southern Kurile Islands. SVERT is a project within the Institute of Marine Geology and Geophysics, Yuzhno-Sakhalin, Sakhalin Island. SVERT is modeled on, but not identical to KVERT. Marina Chivisova provided a catalog of volcano locations for the Kurile Islands. Dates of the last eruption were provided by T. Neal of the Alaska Volcano Observatory (personal communication) citing data sources: (1) Alexander Rybin and Marina Chibasova, IMGG (working from Russian maps at scales of 1:50,000 and 1:200,000), (2) Simkin, T., and Siebert, L., 1994, Volcanoes of the world, Tucson, Arizona, Geoscience Press, Inc., 349 p; (3) the on-line database of the Global Volcanism Program of the Smithsonian Institution (<http://www.volcano.si.edu/gvp/world/index.cfm>). Some inconsistencies between sources remain unresolved, as reported by T. Neal. It is inferred that definitions of an "Active Volcano" are in SVERT parallel the definitions in KVERT. All of the locations were entered into a database, converted to decimal degrees, plotted in a GIS, and visually checked for accuracy. Indicated locations were compared to topographic features seen on the USGS GTOPO30 digital elevation model. Locations were also compared to georeferenced digital overlays of location maps found on the KVERT, IVS and AVO websites. <http://www.kscnet.ru/ivs/kvert/volcanoes/map.html> (Russian language). <http://www.kscnet.ru/ivs/volcanoes/holocene/main/main.htm> <http://www.avo.alaska.edu/pdfs/Volcanoes_svert_en.pdf> The Smithsonian Global Volcanism Project was consulted to resolve the few cases where discrepancies were noted between published coordinates and maps. The Smithsonian coordinates are more accurate than the KVERT and SVERT coordinates in terms significant figures of decimal degree locations, and in correspondence with topographic features. The Smithsonian coordinates were therefore generally used as the final value, where the Smithsonian database contained location data for the identical peak described by KVERT and SVERT. In most cases this resulted in a shift of 1-2 km from the original locations, substantially less than the symbol size used on the published maps. In rare instances where the Smithsonian data was only given to one-tenth decimal degree, the location was refined to the nearest one-hundredth decimal degree by referencing the topography.

    Data sources used in this process:

    • Girina, O.A., and KVERT staff, 2010
    • Chivisova, M. and SVERT staff, 2010
    • Neal, C.A., 2010
    • Smithsonian National Museum of Natural History staff, 2010

  3. What similar or related data should the user be aware of?


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

  1. How well have the observations been checked?

    This data is considered to be a comprehensive and thorough compilation of all available data. See process steps for a detailed discussion of the steps taken to ensure attribute accuracy.

  2. How accurate are the geographic locations?

    The horizontal positions are reported to as many decimal degrees (at least 2, and up to 3) as the author feels the location can be confidently known. Longitude and latitudes were compiled from existing published resources and plotted using a GIS to visually verify accuracy. Locations were plotted with GIS on the USGS GTOPO30 digital elevation model to visually verify accuracy with topographic features. Location data provided by KVERT and SVERT were provided in degree-minute format. Although the data are given to the nearest minute, inspection of the data suggests that the coordinates are generally accurate to the closest 1/6 degree. Maps from KVERT and AVO were georeferenced and digitally rendered as transparent overlays as a second process to verify accuracy of locations. Where published locations of volcanic features appeared inaccurate, locations were validated by comparing maps and coordinates from multiple sources. Data from the Smithsonian Volcanism Project was generally selected as the most accurate source, and used for all volcanoes where an exact match existed to the KVERT and SVERT tables. The Smithsonian data are generally given to the nearest hundredth or thousandth of a decimal degree.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This data lists active volcanoes of Kamchatka and the Kurile Islands, their location in latitude/longitude decimal degrees, and the year of the last eruptive event. The 65 volcanoes listed meet at least one of the following criteria: 1) A historically documented eruption, or 2) a state of fumarolic activity, but without a historically documented eruption, or 3) potentially active volcanoes which have erupted in the past 3500 years (from dating of the last eruption). It is assumed that the definition of "active volcano" in data from SVERT parallels the definition from KVERT.

  5. How consistent are the relationships among the observations, including topology?

    Location points were visually examined to ensure correct placement relative to the base layer.
