In our county, which is called the volcanic country, there are many water-supply facilities even near the volcano. At the period of volcanic activity, sometimes these facilities are suffered by volcanic hazards. Aspects of volcanic hazards are various ; resemble earthquake, flood, big-fire and explosion hazard, and further indude contamination of sub-water. In this paper, the author tries to investigate the damaged facilities, to debate on the countermeasures for hazard prevention and to examine the facilities by using hazard-map of volcanic zone. ƒL�[ƒ��[ƒh�i‰p�j�F - ‹LŽ–‹æ•ª�F - ‹æ•ª �@�@�@ˆÏˆõ‰ï˜_•¶�W
