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. By clicking the "License Request" button, the full set or individual layers can be requested freely for research and public-good applications, or for a licensing fee in the case of commercial applications.

The Global Seismic Risk Map (v2023.1) poster comprises three global maps, and a ranking of the top 15 countries according to five risk metrics. The main map presents the geographic distribution of average annual loss (AAL) of built-up area due to ground shaking in the residential, commercial and industrial building stock. It does not consider the effects of tsunamis, liquefaction, landslides, and fires following earthquakes. These results are an update of the global maps released in 2018, as described in Silva et al. (2020) and are based on best available and publicly accessible datasets and models, which have been collected, curated and maintained in collaboration between local experts and GEM Foundation scientists. The underlying dataset used to create the main map can be requested as a shapefile for use in research and public-good applications without cost, or for a licensing fee in the case of commercial applications. In addition to the AAL of built-up area depicted in the poster, the underlying dataset also includes estimates of average annual economic losses, number of buildings lost, population left homeless and fatalities.
