Greenland) are currently not covered by a hazard model. Overall the differences between the original and translated model results are small, notwithstanding some diversity in modelling methodologies implemented in different hazard modelling software.
While translating these models, various checks were performed to test the compatibility between the original results and the new results computed using the OpenQuake engine.

The map is based on a database of hazard models described using the OpenQuake engine data format (NRML) those models originally implemented in other software formats were converted into NRML. A smoothing methodology was applied to homogenise hazard values along the model borders. The OpenQuake engine, an open-source seismic hazard and risk calculation software developed principally by the GEM Foundation, was used to calculate the hazard values. The map was created by collating maps computed using national and regional probabilistic seismic hazard models developed by various institutions and projects, and by GEM Foundation scientists.
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).
