The Global Earthquake Model (GEM) Global Seismic Hazard Map (version 2023.1) 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). The map was created by collating maps computed using national and regional probabilistic seismic hazard models developed by various institutions and projects, in collaboration with GEM Foundation scientists. This version represents an update from the previous release from 2018 and features improvements in most regions of the world, as well as a higher spatial definition (approx. 2.5X) compared to the previous version. For the first time, it is now openly available in raster format as a direct download under a CC BY-NC-SA 4.0 license. An interactive online viewer (CC BY-NC-SA 4.0) is available, as well as a PDF poster and a high resolution PNG (CC BY-SA 4.0) through the links in this page. A set of comprehensive maps is also available that features up to 20 layers with global coverage, considering PGA and spectral acceleration (SA) for four periods of vibration (0.2s, 0.3s, 0.6s and 1.0s), calculated for reference rock and spatially variable soil conditions, for 2% and 10% probability of exceedance in 50 years.
