Global earthquake maps
The development of the Global Earthquake Hazard and Risk Model was a key priority for GEM under its 2014-2018 Work Program. The objective is to collaboratively develop a complete set of earthquake data and models, and to deliver a comprehensive global assessment of earthquake risk.
Global Earthquake Hazard Map
The Global Earthquake Model (GEM) Global Seismic Hazard Map (version 2018.1) depicts the geographic distribution of the Peak Ground Acceleration (PGA) with a 10% probability of being exceeded in 50 years, computed for reference rock conditions (shear wave velocity, Vs30, of 760-800 m/s).
Global Earthquake Risk Map
The Global Seismic Risk Map (v2018.1) comprises four global maps. The main map presents the geographic distribution of average annual loss (USD) normalised by the average construction costs of the respective country (USD/m2) due to ground shaking in the residential, commercial and industrial building stock, considering contents, structural and non-structural components.
