* National Research Institute for Earth Science and Disaster Prevention 1. Outline
This database, “Volcanic Hazard Maps of Japan,”
covers almost all hazard maps and disaster prevention maps published from 1983 to March 2013 for 40 active volcanoes in Japan. It also includes the old versions of the maps and explanatory references.
The enclosed DVD contains 319 reference materi-als, including those covered by the first edition, which was published in 2006, and those collected thereafter.
The DVD also contains 56 hazard maps plus 27 related reference materials for which approval has been newly obtained from the institutions and committees that pre-pared them, and it contains regional disaster prevention plans and volcanic disaster prevention plans for which usage permission has been obtained. Y. Hotta controlled the entire process of preparing the references and edited illustrations and papers. K. Sawai collected the maps and references and prepared the “List of Database on Volca-nic Hazard Maps and Reference Material”, and H. Suzuki supervised the creation of the html files and web pages.
Technical Note of the National Research Institute for Earth Science and Disaster Prevention, No. 380 ; July, 2013 b) the same HM or RM when they differ in terms of
only the year of issue, not the contents, and the pub-lication year of the first edition is cited in second and subsequent editions as the original year of issue c) In the case of HMs or RMs reprinted because of a
misprint, only the correct version is included in the database
(4) Naming of files
The files have been named in the following manner:
Example: \05atosa_1h01-H.pdf
[Volcano ID + name of the volcano]_[1: whole; 2: re-gional][h: hazard map; m: reference material][two-digit serial number] -[L: low resolution, H: high resolution]
3.2 Order in which HMs and RMs are arranged
(1) In the “Name of hazard map / Reference material”
list, HMs and RMs are arranged in order of volcano number. The volcano numbers and names in the list are based on the “National Catalogue of the Active Volcanoes in Japan, 4th Edition” (Japan Meteorologi-cal Agency, 2012). The rank of volcanic activity is based on the “National Catalogue of the Active Vol-canoes in Japan, 3rd Edition” (Japan Meteorological Agency, 2005).
(2) For each volcano, HMs and RMs are arranged in or-der from the whole to the regional editions. In each class of information, HMs are listed first and then RMs.
(3) RMs and HMs of the same edition type are each ar-ranged in the reverse chronological order in which they were published.
(4) If there are two or more regional editions for a single region, the HMs and RMs are arranged in the order of the relevant publisher, i.e. from national, through prefectural, to municipal governments. HMs and RMs published by different municipal governments are placed in random order.
(5) Reference numbers were newly assigned for this second edition of the database and are different from those in the first edition.
3.3 Explanation of columns
(1) Common: Description in parentheses indicates in-formation not shown in the original text but added in the second edition for clarification.
(2) Regions: Japan is divided into four blocks: Hok-kaido, Tohoku, Kanto and Chubu, and Kyushu. Vol-canic hazard maps have not been prepared for other regions.
(3) Volcano number and name of volcano: Based on the “National Catalogue of the Active Volcanoes in
Japan, 4th Edition” (Japan Meteorological Agency, 2012)
(4) Rank (Rank of volcanic activity): Based on the “Na-tional Catalogue of the Active Volcanoes in Japan, 3rd Edition” (Japan Meteorological Agency, 2005) (5) Name of hazard map/Reference material: The file
you wish to browse will open when you click on the name of the HM or RM.
(6) Pagination: Information on pagination for reassem-bling separately scanned image sections (if any) into an entire image is displayed below the name of the HM or RM. Please see “Notes for printing,” which can be reached via a link on the opening screen, for methods of image reassembly.
(7) Size and/or kind of reference material: Indicates the original size and/or form of the reference material.
(8) Kind of materials: Expressed as a combination of a number and a letter, i.e. 1: entire edition or 2: region-al edition + h: hazard map or m: reference materiregion-al.
(9) File size for print: Represents the size of the file in Mb, with resolutions of 300–400 dpi. The file size is prefixed with a ▼ mark if the file includes images at resolutions below 300 dpi. Files for which resolu-tion is unidentified are marked with , showing that printing quality is not guaranteed.
(10) Publisher/reference: If the publisher or reference has their own website, click on the publisher/reference column to access the website.
(11) Date of publication: The notation of the date of the publication has been standardized by using the West-ern calendar. If the date of publication is not written on the HM or RM, “not written” is shown in the column and any additional information or materials obtained from the publishers by our clerical staff is added in parentheses.
(12) Explanation of volcanic alert levels: A link is provid-ed to a leaflet on volcanic alert levels on the website of the Japan Meteorological Agency.
4. Regional disaster prevention plans
The database covers the regional disaster prevention plans cited by municipal governments as of December 2012. Many municipal governments revise their regional disaster prevention plans annually and make frequent changes to them. In principle, links are posted to the di-saster prevention plan pages of those municipalities that have such plans posted on their websites. In the case of those municipalities that do not have plans on the web but have given us their plans and permission to use them, the plans are included in the database as PDF files. These PDF plans are not the latest versions, and users should
Explanation of “Volcanic Hazard Maps of Japan – Second Edition” — Y. HOTTA et al.
ask the relevant municipality for the latest version every time they want to use it. In the case of plans that we did not obtain permission to use, only the names are listed in the database.
5. Volcanic disaster prevention plans, emergency sabo plans for mitigating volcanic eruption disasters, etc.
Volcanic disaster prevention plans, emergency sabo plans for mitigating volcanic eruption disasters, and other relevant plans as of December 2012 have been collected and included in the database. In the case of those plans
that we were unable to get permission to use, only the plan names are listed.
Acknowledgments
We thank the municipal governments and institutions involved in volcanic disaster prevention for helping us to collect volcanic HMs, RMs, regional disaster prevention plans, and information on Volcano Disaster Management Councils. We are also grateful to Ms. N. Hiyama of the National Research Institute for Earth Science and Disas-ter Prevention for her help in editing papers.
