Analogue models of caldera resurgence: database of models and elaborations

This dataset presents the results of an experimental series of analogue models performed to investigate caldera resurgence processes, particularly the setting of the Los Potreros caldera that belongs to the Los Humeros Volcanic Complex (Puebla State, Mexico). Our experimental series was designed adopting a parametric approach, which consisted in the systematic variation of controlling parameters, such as: depth of intrusion, overburden thickness above the analogue magma chamber, presence of inherited discontinuities. Structures of models have been analysed quantitatively by means of (i) photogrammetric Digital Elevation Model reconstruction, (ii) semi-automatic fault pattern quantification and (iii) Digital Particle Image Velocimetry techniques. In this dataset, we show the row data and specific elaborations supporting the interpretation of modelling results.
