Updated (October 2022) version of supplementary files for running probabilistic seismic hazard analysis (PSHA) MATLAB codes for Malawi. The PSHA codes themselves (v1.0) are available at: https://doi.org/10.5281/zenodo.7265781and the most recent version will be available on GitHub at: https://github.com/jack-williams1/Malawi_PSHA. Note the variables stored here are not stored on GitHub due to the file size. Includes both input files for performing PSHA and output ground motions for plotting PSHA results. Files are: malawi_Vs30_active.txt: Input USGS slope-based Vs30 values for Malawi (Wald and Allen 2007) EQCAT_comb.mat: MSSM Direct catalog for all possible rupture weightings (stored as MATLAB variable) GM_MSSM_em_20221027: Ground motions for plotting PSHA maps (stored as MATLAB variable) GM_MSSM_20221021.mat: Ground motions needed for plotting PSHA-site analysis figures (stored as MATLAB variable) mssm_comb.mat: Matlab file for combined MSSM Direct and Adapted MSSM catalogs (stored as MATLAB variable) MSSM_Catalog_Adapted_em.mat: Adapated MSSM event catalog (stored as MATLAB variable) syncat_bg.mat: Areal source stochastic event catalog (stored as MATLAB variable) Further descriptions of these files and how to use them are provided on Github. An open-access manuscript describing the PSHA is available at: Williams J. N., Werner M. J., Goda K., Wedmore L. N. J., De Risi R., Biggs J., Mdala H., Dulanya Z., Fagereng Å, Mphepo F., Chindandali P. (2023).
