Global Vulnerability Model
Sets of functions to assess the consequences of earthquakes on the built environment of the world
Description
The Global Vulnerability Model (v2023.1) consists of a set of functions that estimate the consequences of earthquakes of a given intensity to different building typologies. This model includes curves to assess economic losses, divided into structural, non-structural and content losses, as well as estimates of fatalities.
The database is separated by region-country/territory and considers functions for over 3500 building typologies identified in the Global Exposure Model developed, curated and maintained by the GEM Foundation.
The fragility functions are derived analytically, using non-linear time-history analyses on equivalent single-degree-of-freedom oscillators and a large set of ground motion records representing several tectonic environments.
The entire database is available for direct download under a CC BY-NC-SA license for risk modelers, analysts and researchers to perform seismic risk assessment on their portfolios.
