This dataset collects the results of a series of experiments carried out on air-filled cracks injected into pigskin gelatin blocks between September 2019 and May 2020 at GFZ German Research Centre for Geosciences in Potsdam (Germany). Such experiments were intended to simulate dike propagation in the upper crust, in settings where tectonic and surface unloading stress are dominant in determining the stress field within the medium. The gelatin blocks were laterally strained and rift-like excavations were moulded on their surfaces.

These data include pictures of each experimental setup and video records of each injected crack, as well as tables collecting the measured arrival points of the cracks at the surface of the gelatin and relevant elastic and geometric parameters.

The data publication is a Supplement to Mantiloni et al. (2020): "Stress inversion in a gelatin box: testing eruptive vent location forecasts with analog models" (Geophys. Res. Lett.), to which the reader is referred for further information.
