Global Earthquake Model (GEM)

For a world that is resilient to earthquakes

Global Earthquake Model (GEM)

The Global Earthquake Model (GEM) Foundation was established to create an independent, uniform, and openly accessible standard for calculating and communicating seismic risk worldwide and for developing much-needed tools and software such as OpenQuake, earthquake hazard and risk models, and associated databases for reliable and transparent seismic risk assessment globally.

Formed in 2009 as a nonprofit organization in Pavia, Italy, GEM is comprised of an international community of scientists and professionals, supported by a public-private sponsorship with a vision to create a world that is resilient to earthquakes.

GEM Models

The GEM Colombia model is based upon GEM’s regional model for South America first developed from 2013 to 2015 within the South America Risk Assessment (SARA) project funded by the Swiss Re Foundation and updated in 2018. The development process involved dozens of local scientists and engineers from earthquake-prone countries in South America, resulting in an open product for analyzing ground-up loss from ground shaking for residential, commercial, and industrial buildings. This model has been further improved with local information, such as local construction practices, replacement costs and level of enforcement of the seismic regulations.
