Abstract
Caldera forming eruptions are characterized by a large-scale and low frequency. To prepare for them, monitoring of volcanic activity is insufficient for practical evaluation. Volcanic activity generally involves two end members, one in which an eruption dominates and one in which geothermal activity dominates, as defined by the ease in magma ascent. Caldera forming eruptions tend to be prepared where magma stagnates easily. Research on stop of magma ascent and its accumulation is required to understand caldera forming eruptions.
