Focal mechanism catalog supporting: Stress variability and kinematic segmentation in the Atacama segment revealed by high-quality focal mechanisms

"This repository contains the dataset and configuration files supporting the manuscript titled "Stress variability and kinematic segmentation in the Atacama segment revealed by high-quality focal mechanisms". The dataset provides a high-resolution catalog of 89 focal mechanisms derived from a dense regional seismic network recorded between 2020 and 2025. The contents are structured as follows: /input_SKHASH: Contains the earthquake source parameters, P-wave polarity picks, station metadata, and the local 3D velocity model (vel_atacama.txt) used for wave propagation. It also includes the control_file.txt with all specific inversion parameters. /output_SKHASH: Includes both the raw inversion results (out_skhash.csv) for the initial 602 events and the final filtered catalog (catalog_best_results.txt) of 89 high-quality mechanisms used in the tectonic interpretation. /spherograms_best_results: Contains the individual stereograms (beachballs) for the 89 final focal mechanisms, providing visual evidence of the P-wave polarity fit. The focal mechanisms were computed using the SKHASH Python package, integrating manual picks with a 3D non-linear relocation model. This repository is provided for peer-review access. Upon acceptance of the manuscript, these data will be formally archived with a persistent DOI."
