Abstract
More than ten thousand inhabitants were obligated to stay in temporary dwelling for a long time without their ordinary works during the eruption of the Mt. Fugen in Unzen erupted on 17 November 1990. The long-term volcanic activity rendered severe bad effects on the local economy in commerce, industry, agriculture and fishery as well as sufferers from volcanic disaster. Governments made effects to support the sufferers.
In present paper, measures for relief systems are investigated in detail and discussed.
