GEM Global Risk Model Documentation#
The GEM Global Risk Model provides a comprehensive framework for assessing earthquake risk worldwide, integrating hazard, exposure, and vulnerability data to quantify potential impacts. This documentation covers:
Exposure models (population and building stock for residential, industrial and commercial sectors),
Vulnerability functions (fragility, damage-to-loss and vulnerability relationships for different loss types),
Impact results (fatalities, economic losses, damaged buildings, injuries, affected, and displaced population).
Designed for researchers, policymakers, and disaster risk practitioners, the model supports data-driven decision-making through open data, transparent methodologies, and globally consistent risk metrics. Explore the sections in this documentation for detailed model descriptions, datasets, and applications.

For further documentation on a given region, country or territory, please refer to the regional page. Note that documentation of our models is an active work in progress, thus some sections may not yet be populated with information.
The authors are grateful for the input from dozens of local and international experts. A list of contributors can be found on the Contributors page.
