Overview of Japan Volcanological Data Network (JVDN)

There are 111 active volcanoes in Japan. While active volcanoes give us the grace of hot springs, geothermal power generation and so on, there are also cases where eruptions can cause disasters. To understand volcanic phenomena through volcano observation and survey is indispensable for residents to live with active volcanoes by mitigating disasters. In Japan, universities, research institutes, administrative organizations have conducted volcano observations according to their respective roles, promoted distribution and sharing of observation data, and collaborated with each other to contribute to the promotion of volcano research and volcanic disaster mitigation. JVDN strengthens its cooperation, promotes volcano research, and contributes to volcanic disaster mitigation. Major related organizations such as NIED, Universities, JMA, AIST, GSI, local research institutes and etc. are participating in JVDN (under discussion). Various observation data of each institution is stored in a database and shared through visualization tools to promote collaborative research through multi-disciplinary collaboration and cooperation between organizations. Furthermore, we contribute to volcanic disaster mitigation through collaboration between volcano research community and disaster prevention organization. The international standard WOVOdat database promotes cooperation with overseas research institutions. Volcanic researchers in Japan will continue to conduct research on volcanoes throughout Japan, not only in individual fields and volcanoes, but also contribute to the development of global volcanic research through international cooperation. The WOVOdat database also functions as an index of the database of each institution and provides users with access to raw data. JVDN is being developed by a development team centered on NIED in the next generation volcano research promotion project by MEXT.
