The rationale behind constructing this new database is to create a comprehensive catalogue including all known or identified collapse calderas. The availability of accurate and comprehensive statistics is vital to understand these volcanic structures . Thus, this extensive data compilation should be an accessible and useful tool for studying and understanding caldera collapse processes . The final aim of the CCDB is to update the current field based knowledge on calderas, by merging together the abovementioned databases and complementing them with the existing peer-reviewed articles on calderas. This database does not include all the calderas of the world but tries to be representative and will remain open for further updates. In this paper, we present an example of the CCDB applicability. For instance, we show how the information included in the CCDB allows us to find out if there exists any correlation between the different characteristics of collapse calderas (e.g. morphology, age, dimensions, etc), in order to establish similarities and differences among the different calderas recorded in the database.
