The volcano of Eyjafjallajökull in Republic of Iceland which is located in 125km east of Capital Reykjavik erupted on April 14, 2010. The eruption column reached the stratosphere of 10, 000m or more in the atmosphere, and volcanic ashes had been diffused by the air current in high altitude to the whole land in west Europe. The volcanic ash clouds caused the confusion of the aviation in the airports in Europe. The airports of about 30 countries in Europe closed temporarily, and 100, 000 aircraft flights a week interrupted operations. The confusion of the airline consequentially exerted a large influence on an international economic activity centering on Europe.Japan is one of the eminent volcano countries in the world and the large-scale eruptions were recorded at the surrounding of the eastern Asia in the past. Recently, a human movement by the aircraft has been activated according to remarkable economic development in the eastern Asian countries, which are connected in the supply chain. In such a circumstance, the influence by a large-scale volcanic eruption to the aircraft is not neglected. In this study, we prepare the assumption scenario of the volcanic ash clouds in the future to investigate the influence reduction of the civil aviation and the related facilities as for the large-scale eruption.
