volcanic hazard map was published in March ,**,, and in June ,**,, it was distributed to the inhabitants ofKamitakara village, Gifu prefecture, where is located .῍,* km west from the volcano. In January ,**-, thequestionnaire survey was carried out on the inhabitants in order to know their attitudes to the volcanic hazard map
and the level of their understanding of the contents of the hazard map. The Kamitakara village o$ce distributed
the questionnaires to +,+*, families through the headman of each ward, the headman collected 2*, answers. The
results of analysis were as follows. 23ῌ of the respondents knew the existence of the hazard map and -/ῌ read
it well, but about ++ῌ have not read the map at all. The elders have a tendency to have deeper understandingof the hazard map than younger ones, especially in elders who have experiences to meet some kinds of natural
hazards. And the people who once attended the explanatory meeting of the hazard map, which was held for theresidents living inside the disaster-prone area four times after the publication of the hazard map, also tend to havemore proper understandings. The people who are engaged to the tourism give more attention to the volcanic
hazard than others. The respondents have strong tendency to require more knowledge about the volcanic
activities and hazards. We can say that the further activities by scientists, engineers and administrative o$cers
are expected in order to establish an informed consent, that is, there should be a decision-making by inhabitants
themselves and support by o$cers in charge with detailed explanations.
