Abstract

This study investigates the damages of and analyzes the social and economic impacts of volcanic ash eruptions in the world in order to estimate the potential volcanic ash impacts in South Korea when Mt. Baekdusan volcano erupts in the future. First, we build a comparison chart called "the impact of volcanic ash" on each economic and social sector by using major volcanic eruptions and we compare the damage with respect to volcanic ash thickness/weights. Secondly, we analyze the social and economic impact from volcanic ash. The economic damage is not likely to occur in South Korea, unless Mt. Baekdusan erupts in winter. However, the potential damage should not be overlooked because the volcanic ash may have a global impact around the world. If Mt. Baekdusan volcano erupts when the wind blows from north or northeast, the volcanic ash may then significantly affect South Korea of which economy is highly dependent on exports. Particularly when the volcanic ash moves to the densely populated metropolitan areas or agricultural areas, the damage can be significant. In preparation for the potential volcanic disasters, the volcanic ash forecast table suitable for South Korea should be prepared. In addition, building a Korean volcanic ash hazard map in advance will have a strategic significance.

백두산 화산이 분화할 경우, 한국에는 주로 화산재로 인한 피해가 예상된다. 이에 본 연구는 해외의 대형 화산분화 사례를 기반으로, 화산재 규모에 따른 피해와 사회 경제적 영향을 분석하였다. 첫째, 주요 화산 분화의 화산재 피해사례 및 화산재 두께/무게에 따른 피해를 "화산재 규모와 피해 영향 대조표"를 통하여 살펴보았다. 둘째, 화산재의 사회 경제적 영향을 분석하였다. 백두산이 겨울에 분화하지 않는다면, 한국은 화산재로 인해 경제적 피해를 입을 가능성이 크지 않지만, 화산재의 특성상 범세계적으로 영향을 미칠 수 있기 때문에 그 영향을 간과해서는 안 된다. 한편 만약 백두산 분화 시기에 한반도 주변으로 북풍 또는 북동풍이 발달하면, 화산재가 남한으로 확산하여 남한 경제에 영향을 미칠 수 있다. 항공수출에 차질이 생길 수 있으며, 인구 밀도가 높은 수도권이나 지방중심도시(산업집중도시) 혹은 농업지역으로 화산재가 이동해 온다면 그 피해는 매우 클 수 있다. 이러한 화산재해에 대비하여 한국의 실정에 맞는 화산재 예보 단계표가 만들어야져야 하며, 화산재 예측을 위한 한국형 화산 해저드 맵을 구축할 필요가 있다.
