The Hokkaido-Komagatake and Mt.Tarumae are one of the most active Volcanoes in Japan. Because the process of eruption the two volcanoes may take cannot be specified, the residents will be required to evacuate at an early stage of eruption event. We suppose that only the high preparedness and highly awareness of risk can evacuate early. Two mass surveys and the interview survey were conducted in order to identify the social-structural factors that the determine the level of the disaster preparedness.The first mass survey made inquiries into the 439 residents who live near the Hokkaido-Komagatake, and second one 211 citizens of Tomakomai city near the Mt.Tarumae. We interviewed twelve community leaders in order to investigate the awareness of the eruption risk and responses against small-scale events of the Hokkaido-Komagatake in 1996-2000. Major finding are outlined below.1.Compared with the survey conducted by Tazaki(1988), the residents raised the level of preparedness and risk evaluation.2.They expressed considerable interest in the small-scale events of the Hokkaido-Komagatake in 1996-2000 and the eruption of the Mt.Usu in 2000, and most had a conversation with their neighborhood, especially fellow workers.3.They are inclined to depend on highly Local Governments' evacuation order. And they are also inclined to believe erroneously that the eruption will proceed in a similar manner as before or that the eruption would occur periodically.4.Those who are highly concerned for the volcano eruption are inclined to prepare well. But even though they feel anxiety, they aren't sure to prepare for eruption.5.Those who involve in community actively are inclined to prepare highly for the eruption.6.n the community with highly cohesiveness, it seems that the "Frame Augmentation" strategy, Resource Mobilization Theory proposed, are used, and in low cohesive community "Frame Extension" strategy tends to be used.
