Abstract

There has been a growing interest on the effect of volcanic eruption on the aviation safety, air travel and economy especially after the eruption of Eyjafjallajokull in Iceland. Since volcanic eruption is influential on a large geographic region, the effect usually extends to other neighboring countries. Korea also has an active volcano named Mountain Baekdu. Hence, the need to estimate in advance the quantitative impact of the potential eruption of Mt. Baekdu on South Korean air transportation system. However, previous studies with quantitative estimation were confined to the calculation of the direct economic loss from shut down of the airports, grounding of airlines, and trade deficits caused by the eruption. Therefore, this paper introduces a new approach to assess more accurate impact simultaneously considering volcanic ash dispersal and aviation routes. This approach is then applied to a virtual scenario to predict the damage to air traffic. With further development, this method can help estimate the damage in the air transportation industry in more accurate and faster ways. Prediction outcomes can also be utilized in setting up the emergency response plan for the air transportation industry and contribute to the creation of more proactive and predictive measures in the future.

아이슬란드 화산폭발에 따른 항공대란 이후, 화산 폭발에 따른 항공 안전, 여행 및 경제 등의 관심이 증가되고 있다. 화산폭발의 경우, 화산재 화산에 따라 폭발 지역 뿐 아니라 인근 국가의 항공교통과 산업까지도 영향을 끼친다. 국내 주변에는 활화산인 백두산이 있으며, 백두산이 폭발 했을 경우의 국내 항공교통에 미치는 피해량을 예측하여 사전에 대응할 필요가 있다. 국내에는 화산재에 대한 항공교통의 피해량을 실제로 정량화하여 피해를 예측한 연구로는 공항의 폐쇄일수, 결항된 운항편수 및 무역 적자 등의 경제적 손실로만 분석하고 있다. 본 연구는 백두산폭발에 따른 확산모형과 항공로를 결합한 정량적 피해 산출 알고리즘 도출과 가상의 시나리오를 통하여 피해량을 예측함에 그 이의가 있다. 관련 알고리즘은 시스템 개발을 통하여 항공교통피해 예측을 보다 정확하고 신속하게 도출할 수 있을 것이다. 또한, 예측된 항공교통 피해량은 향후 항공교통 대응체계 수립을 위한 기초자료로서 활용이 가능할 것이며, 항공 산업의 선제적 예측적 대응방안에 기여할 수 있을 것이다.
