Modelled Coulomb failure stress changes for 62 locations of circum-Antarctic faults since the last glacial maximum

The folders contain files with modelled Coulomb failure stress (CFS) changes in the last 21,000 years for 62 locations of circum-Antarctic faults investigated in Barbosa et al. (2025). The CFS changes are dependent on the characteristics of the tectonic background stress regime, the orientation of a potential fault and the used model of glacial isostatic adjustment (GIA).

We provide two zipped files for strike-slip faulting (SSF) and reverse/thrust-faulting (TF) tectonic background stress regime. The individual file names contain information on the tectonic background stress regime, the fault orientation for which CFS changes are calculated, and the GIA model. Please see Barbosa et al. (2025) for a detailed description of the parameters and the readme.txt for the naming convention.
