Comparison of past InSAR measurements of volcano deformation in Latin America and the rest of the world. a. Proportion of deformation signals attributed to co-eruptive magmatic processes (a), inter-eruptive magmatic processes (b), signals where the distinction between magmatic and hydrothermal processes is ambiguous (c), hydrothermal processes (d), flow deposit subsidence (e) and gravity-driven or faulting-related signals (f). b. Frequency of deformation signals according to inferred reservoir depth for Latin America (blue) and the rest of the world (red). c. Relationship between maximum displacement rate and approximate signal area for Latin America (blue) and the rest of the world (red)
