Calderas and caldera structures: a review
Earth-Science Reviews, 2005Abstract Calderas are important features in all volcanic environments and are commonly the sites of geothermal activity and mineralisation. Yet, it is only in the last 25 years that a thorough three-dimensional study of calderas has been carried out, utilising studies of eroded calderas, geophysical analysis of their structures and analogue modelling

Downsag calderas, ring faults, caldera sizes, and incremental caldera growth
Journal of Geophysical Research: Solid Earth, 1984Not all calderas conform to the currently favored model, in which a cylindrical block subsides as in cauldrons of deeply eroded volcanoes. Some calderas are downsagged structures, a fact deduced mainly from the backtilting of ignimbrite sheets assumed originally to have possessed an outwardly directed slope.

Abstract A study of the formation of Krakatoan-type calderas indicates that they probably form by chaotic collapse. The energy required to form these calderas by explosive decapitation of the volcano is seldom available during caldera-forming eruptions.

The central part of the Island of Pantelleria is occupied by a caldera depression of ellipsoidal form, the major diameter of which is about 7 kilometers. The collapse causing the caldera to form seems to have taken place after a complex eruption which led to the extrusion of a great endogenous dome, the formation of which was followed by a localized ...
