Comment on this resource
This page describes the different types of calderas: Crater-Lake type calderas, which are associated with the collapse of stratovolcanoes; basaltic calderas, which result from the summit collapse of shield volcanoes; and resurgent calderas, which lack an association with a single centralized vent. Each type is described in detail with photographs, maps, diagrams, and examples. Multiple links lead to additional information about each caldera.
