Sub-Saharan Africa Hazard

OpenQuake engine input model to perform hazard calculations for Sub-Saharan Africa

Description

The first version of the hazard model for Sub-Saharan Africa (v2016.0.0) was developed by GEM in collaboration with AfricaArray within the USAID-supported SSAHARA project. The original model is extensively described in Poggi et al. (2017).

Since the original version, extended and improved versions were developed by introducing a procedure of earthquake-driven redistribution of activity rates (smoothed seismicity approach) on the previously defined source zones. Moreover, the current model includes now Madagascar, for which an ad-hoc seismicity analysis was carried out. The latest version (v2018.0.1) was used in the computation of the 2023 Global Earthquake Hazard and Risk Maps, which includes an extension of the minimum magnitude of events for crustal distributed seismicity.
