The seismic hazard model for South Africa (ZAF) was developed by scientists from the Council for Geoscience, South Africa and the Indian Institute of Technology, Jammu, India. The model is described by Midzi et al. (2019). The seismic source model was developed using a newly updated catalogue and consists of zones of distributed seismicity, while the ground motion logic tree consists of two existing ground motion prediction equations (GMPEs) derived for active shallow crust. The model was originally created for the OpenQuake (OQ) engine.

The Western Africa model (WAF) was developed internally by GEM. The model encompasses the whole Atlantic side of the Africa continent. An ad-hoc homogenised earthquake catalogue was developed based on globally available information, which was used as primary base for seismic occurrence analysis and the subsequent development of the source zonation model.

Vulnerability based on the most common building classes in the region; simplified numerical models for each building class; ground motion records using local strong motion databases, local seismicity and tectonic environment; and non-linear time history analysis to evaluate structural response.

Sub-Saharan Africa is part of GEM's Global Earthquake Hazard and Risk Maps released to the public in December 2018. As part of the mosaic, the seismic hazard, exposure and vulnerability models employed in the calculations were either provided by national institutions, or developed within the scope of regional programs, bilateral collaborations, or by GEM.
