User requirements on volcano information published regularly or extraordinary by Japan Meteorological Agency were surveyed by means of interviews and questionnaires in 2001-2003 fiscal year in order to grasp issues on the volcano information and to find keys to improve them. This paper unveils the result of surveys on volcano information of Fuji Volcano, for which JMA has published no volcano information because of its continuous low volcanic activity, and gives fundamental considerations on how information about Fuji Volcano should be dispatched.
After analysis of the series of survey data, users' expectations of unhesitating publishing volcano information and those of special handling for Fuji Volcano are observed. Applying volcanic activity level, which is issued for five active volcanoes in Japan, would contribute to reduce users' difficulties in understanding volcano information of Fuji Volcano.
We also analyzed how the low volcano literacy of the local governments and residents around Fuji Volcano bars effective use of volcano information. Providing residents with an opportunity to improve fundamental knowledge on volcano disaster prevention should be an effective measure in preparation for future volcanic crises of Fuji Volcano.
