[SVC27-P07] Production and release of Land Condition Map of Volcano “Zao Zan (Zao San)” and “Yake Dake”
Keywords:land condition map of volcano, landform classification of volcano, Zao Zan (Zao San), Yake Dake
1. Introduction
Since 1988, Geospatial Information Authority (GSI) of Japan has been providing ''Land Condition Map of Volcano (LCMV)'' with a scale of 1/10,000 to 1/50,000, which are useful for predicting volcanic disasters, planning disaster countermeasures, and conducting surveys and research. The map shows the landform classification of volcanoes based on land surface morphology, surface geology, age of formation, origin, etc. In recent years, the map has been developed with priority given to volcanoes (50 volcanoes) that require enhanced monitoring and observation systems for volcanic disaster prevention. The map has been provided for 28 volcanoes as of January 1, 2024.
In this presentation, we will report on the contents and characteristics of the LCMV "Zao Zan (Zao San)'' and ''Yake Dake'' that will be developed from FY 2022 to FY 2023 and scheduled to be released in February and May 2024.
2. Outline of products
The LCMV ''Zao Zan (Zao San)'' was created based on the ''Geological Map of Zao Volcano'' (Ban et al., 2015) and the results of interviews with officials of the Mt. Zao Volcanic Disaster Prevention Council and experts. The area covered is a radius of about 4 km centered around Okama near the summit of Mt. Zao, and a belt-shaped area from there to the vicinity of Togatta Onsen, where the Nigori Kawa River flowing east, for a total area of about 64 km2. The scale of the map was created at 1/20,000.
The LCMV "Yake Dake" was created based on the 1:50,000 geological map "Kamikochi" (Harayama, 1990), the literature on the geology of the Yakedake volcano group (Oikawa, 2002, etc.), the interviews with officials of the Mt. Yakedake Volcanic Disaster Prevention Council, and discussions at a review committee of experts. The area covered was about 60km2, centered on the summit of Mt. Yakedake, and including Mt. Akandana, Okuhida Onsengo Hot springs and Kamikochi area at the foot of the mountain. The scale of the map was created at 1/25,000.
For both volcanoes, the volcanic landform was classified based on the interpretation of aerial photographs and detailed digital elevation model data obtained from airborne laser surveys, with reference to information on volcanic geology. We also incorporated erosional landform and gathering landform into these maps with consideration for use in volcanic erosion control, etc.
3. Products
Figure 1 shows the LCMV ''Zao Zan (Zao San)''. Please note that the map of ''Yake Dake'' may not have been published at the time of publishing this article, so we refrain from publishing it. The paper size is A1 for ''Zao Zan (Zao San)'' and A2 for ''Yake Dake''. These maps will be available for viewing on GSI Maps. Additionally, we plan to provide on-demand inkjet output maps for a fee from the Japan Map Center, and to provide free image data (JPEG format) and numerical data (shapefile format, etc.) from the GSI of Japan's website.
4. Summary
From FY 2022 to FY 2023, we produced LCMV ''Zao Zan (Zao San)'' and ''Yake Dake'' and prepared them for release in February and May 2024. The image data and numerical data that will be provided free of charge from the GSI of Japan's website, as well as the paid inkjet output maps, are expected to be used in future studies of volcanic disaster prevention, volcano research, and education.
Acknowledgements: We would like to thank Professor Masao Ban of Yamagata University and the secretariat of the Mt. Zao Volcanic Disaster Prevention Council for their help in creating the LCMV "Zao Zan (Zao San)''. In creating the LCMV "Yake Dake," we received advice from expert review committee members Professor Takeshi Saito of Shinshu University and Associate Professor Shusuke Miyata of Kyoto University, as well as Professor Emeritus Satoshi Harayama of Shinshu University and the secretariat of the Mt. Yakedake Volcanic Disaster Prevention Council.
