Statistical data analysis of the CCDB (Collapse Caldera Database): Insights on the formation of caldera systems

►Non parametric one-way ANOVA on a sample from the Collapse Caldera Database (CCDB). ►The area of calderas depends on the geodynamic environment where they develop. ►Three Caldera Area groups based on crustal type, rock suite, plate tectonic setting. ►Groups have significantly different Caldera Area based on Kruskal-Wallis test. ►The dynamics of the volcanic system are related to the geodynamic environment.
