Abstract
This data set includes the results of digital image correlation of 21 analogue experiments on isostatic relaxation of the crater floors performed at UHH-Tec Modelling Laboratory of the Universität Ham-burg. The structural evolution of model upper crust was systematically analysed for various initial depths and diameters of crater floors, gleaned from numerical models for average continental crust. The experiments show that crater floor uplift is accomplished by long-wavelength subsidence of the crater periphery and may operate on time scales of thousands of years in nature. Detailed descriptions of the experiments and monitoring techniques can be found in Eisermann and Riller (2024) to which this data set is supplementary. The data presented here consist of movies and images displaying cumulative displacements of deforming analogue model surfaces.
