1. This document is a supplement to the article ‘Large near-surface block rotations at normal faults of the Iceland rift: evolution of tectonic caves and dilatancy’ by Kettermann et al., 2019.
It contains cross-plots and histograms of measured tilted block dimensions derived from field data in Iceland.
