Welcome to the documentation for the GEM Global Seismic Hazard Mosaic! The mosaic is a collection of 30 national and regional seismic hazard models covering the entire globe. It consists of hazard models developed by various institutions, within collaborative projects, and by the GEM Foundation – all described in a consistent format compatible with the OpenQuake engine. Here you can find a description of every model in the mosaic, a description of the methods used for constructing the hazard models developed by GEM, and information about the release of models and hazard results.
