Model

Northern Africa Exposure

License:

Version:

CC BY-SA

v2022

This dataset introduces a new exposure model for North African countries using national and global datasets with a uniform approach across the continent, developed for a baseline year (2020) and six future years (2025, 2030, 2035, 2040, 2045, and 2050).

Model

Sub-Saharan Africa Vulnerability

License:

Version:

CC BY-SA

v2015

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.

Model

Southern Africa Exposure

v2022

This dataset introduces a new exposure model for South African countries using national and global datasets with a uniform approach across the continent, developed for a baseline year (2020) and six future years (2025, 2030, 2035, 2040, 2045, and 2050).

Model

Northern Africa Hazard

License:

Version:

CC BY-NC-SA

v2018.0.0

The Northern Africa model (NAF) was developed by GEM and is described in Poggi et al. (2020). The model extends from Morocco to Egypt along the Mediterranean coastline. The model consists of a combination of distributed seismicity and faults sources, the former calibrated on occurrence analysis of publicly available earthquake catalogue information, and the latter derived from a thorough evaluation of information from both geological literature and direct analysis of GPS velocity fields.

Model

South Africa Hazard

License:

Version:

CC BY-SA

v2018.0.1

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.
