Caldera collapse vs inherited structures: a database of laboratory experiments

This dataset presents the results of four experimental series of analogue models performed to investigate the role of inherited structures during caldera collapse. Our experimental series tested the role of one/two inherited discontinuities variously located with respect to an analogue magma chamber. Models have been analysed quantitatively by means of (i) photogrammetric Digital Elevation Model reconstruction and (ii) Digital Particle Image Velocimetry (DPIV) techniques. In this dataset, we show the row data supporting modelling results.
