Surface DEM’s data and cross-sections from analogue experiments of subduction initiation performed in the Tectonic Laboratory (TecLab) at Utrecht University

In order to show the spatial and temporal evolution of deformation and associated surface topography, we present our results in terms of surface scans and final cross sections. The latter are pictures recorded at the end of the experiment. They are obtained at two-third of their width. Experiments are monitored using digital photography and laser scans of the top surface. Digital elevation models, DEM's, are used to retrieve the surface data (grid xyz) and evaluate the extent of deformation between consecutive time-steps of the experiments expressed in term of bulk shortening (BS). Vertical movements through time are monitored along topographic profiles to further delineate where deformation takes place. The data is provided in 6 subfolders for 6 experiments. Detailed information about the files in these subfolders as well as information on how the data is processed is given in the explanatory file Auzemery-et-al-2020-Data-Documentation.docx.
