Influence of the Bell-Jar Magma Chamber Geometry on a Caldera Formation

摘要

The formation of a caldera poses a serious risk for the society and the environment. There are several established processes (mostly dealing with the conditions inside the reservoir), which must take place in order to reach a collapse leading to the caldera origin. The role of magma chamber geometry is investigated in this paper, exploiting numerical modeling. The results indicate that the knowledge of the magmatic system geometry can provide a helpful parameter for the assessment of the caldera formation scenario.
