Abstract

Eruptive volumes of three monogenetic volcanoes (Songaksan tuff ring, Biyangdo scoria cone, and Ilchulbong tuff cone) with the youngest eruption age are calculated using the model, applied to Auckland Volcanic Field in New Zealand, to investigate the volcanic eruption scale and to evaluate volcanic hazard of Jeju Island. Calculated eruptive volumes of the volcanoes are $24,987,557m^3$, $9,652,025m^3$, and $11,911,534m^3$, respectively, and the volumes include crater infill, tuff ring (tuff cone), scoria cone, and lava flow. Volcanic explosivity indices of Songaksan tuff ring, Biyangdo scoria cone, and Ilchulbong tuff cone are estimated based on the eruptive volumes to be 3, 2, and 3 respectively, and eruption type is Strombolian to Surtseyan. It is assumed that the amount of emitted sulfur dioxide gas is $2-8{\times}10^3kt/y$ according to the correlation between volcanic explosivity index and volcanic sulfur dioxide index. Recent age dating researches reveal evidences of several volcanic activities during the last 10,000 years indicating the possible volcanic eruption in Jeju Island in the near future. Therefore, it is necessary for appropriate researches regarding volcanic eruption of the island to be accomplished. In addition, establishment of the evaluation and preparation system for volcanic hazard based on the researches is required.

제주도의 화산활동 규모를 파악하고 화산재해를 평가하기 위해 가장 최근에 분화한 단성화산 3개를 선택하여 화산 분화량을 계산하였다. 선택된 단성화산은 송악산 응회환, 비양도 분석구, 일출봉 응회구이며, 뉴질랜드의 오클랜드 화산지대에 적용된 모델을 사용하여 계산한 분화량은 각각 $24,987,557m^3$, $9,652,025m^3$, $11,911,534m^3$이다. 이 분화량은 화구충진물, 응회환(응회구), 분석구, 그리고 용암류의 부피로 구성된다. 분화량을 토대로 추정되는 화산폭발지수는 각각 3, 2, 3이며, 분화유형은 스트롬볼리식(Strombolian) 내지 써제이식(Surtseyan)이고, 화산폭발지수와 화산이산화황지수의 상관관계를 이용한 이산화황 분출량은 $2-8{\times}10^3kt/y$로 추정된다. 제주도에 대한 최근 연대측정자료는 제주도에서 1만년 이내에 화산활동이 수차례 있었음을 보여주며 앞으로의 화산활동 가능성을 지시하고 있다. 따라서 제주도의 분화 가능성을 고려한 연구가 충분히 수행되어야 하고, 이를 토대로 화산재해를 평가하고 대비하는 시스템의 구축이 요구된다.
