Caldera is a large depression commonly formed by collapse of the ground following explosive eruption of a large body of stored magma. On earth, calderas and caldera complexes range in size from kilometers to tens of kilometers. Historical eruptions associated with caldera collapse have led to huge fatalities in Indonesia as well as left global impacts. This study presents case study on calderas in Indonesia which resembles to Mount Baekdu located at the border of China and North Korea; in the perspectives of similar characteristics, principal hazard, recent symptom of volcanic activity and the threat if eruption occurs in the near future. Calculation by using weighted evaluation matrix for Mount Krakatau, Mount Tambora, Mount Ijen, Tengger Caldera, Mount Rinjani and Ranau Caldera were taken for the selection of a site for future case study.

문제 정의
The aim of this work presented in this paper is to obtain Indonesia caldera which resembles to Mount Baekdu for the selection site for future case study in the perspective of similar characteristic, principal hazard, the event of recent volcanic activity and the threat if eruption occurs in the near future. Mount Baekdu and the six candidates of Indonesia caldera were presented in this paper are Mount Krakatau, Mount Tambora, Mount Ijen, Tengger Caldera, Mount Rinjani and Ranau Caldera will be discussed in the following sections.
제안 방법
The work has examined the comparisons among the six calderas in Indonesia which is resembling to Mount Baekdu by using a weighted evaluation matrix for the selection of a site for future case study. Historical eruption associated with caldera collapse led to huge fatalities as well as causing global climatic disruptions.
대상 데이터
The eruption in 1883 produced a series of tsunami which reached up to 40 meters high and smashed into 165 coastal villages in Java and Sumatra caused about 36,000 people perished when those giant waves hit. The explosion was heard to a distance 4,811 km in Rodriguez Island near Mauritius in the Indian Ocean and 3, 224 km away in South Australia. The eruption also caused a large impact on the global climate and temperature dropped as much as 1.
성능/효과
First, caldera criteria are considered e.g. geological setting of the caldera, volcano status, magma characteristic, VEI (historically highest and lowest), potential hazard, number of eruptive events, last known eruption, recent volcanic activity, height of volcano, eruptive characteristic on highest VEI and population within 1000 km. Criteria options are weighted against one another to establish the relative importance factor through a scoring process and a numerical score of 1 to 4 is given to the preferred criteria.
