　The Geologic Map of Volcanoes in Japan (1:200,000) covering details of 440 domestic volcanoes has been developed by Yoshihisa Kawanabe, Shinji Takarada, and Yoshihiro Ishizuka (Research Institute of Earthquake and Volcano Geology) and released on the Web (https://gbank.gsj.jp/volcano/vmap) as the latest database in the “Volcanoes of Japan”.
　To display the distribution of volcanic products and their details with a world-class accuracy, a new database system has been created. It also enables users to zoom in and out the image, search volcanoes and products, narrow down the results, and display a pop-up window of their details such as name and age.
　Learning when, where, and how the volcano erupted in the past provides us important information to mitigate future volcanic disaster and to take advantage of the benefits of the volcano such as geothermal energy. The easy-to-use interface will promote its wide range of application of the database for geohazard mitigation and related research in national and local governments, industry, and academia.

The database is currently available only in Japanese.
