This volume aims at providing answers to some puzzling questions concerning the formation and the behavior of collapse calderas by exploring our current understanding of these complex geological processes. Addressed are problems such as:

- How do collapse calderas form?
- What are the conditions to create fractures and slip along them to initiate caldera collapse and when are these conditions fulfilled?
- How do these conditions relate to explosive volcanism?
- Most products of large caldera-forming eruptions show evidence for pre-eruptive reheating. Is this a pre-requisite to...
