====== The GEM Database of Seismic Hazard Models ======
Here you can find information about the OpenQuake-engine implementation of different seismic hazard models around the world. 

The models provided herein represent GEM's interpretation of the original models proposed by National Agencies and International Projects. These models were created by GEM, in the attempt of reproducing in the most faithful way possible the original models but they ARE NOT intended to be an alternative nor a replacement implementation of the original models. 
 
GEM provides them recognising importance, authoritativeness and, transparency of the original models, for the purpose of open collaboration and in the hope that it will be useful to the scientific, engineering, disaster risk and software design communities.

Scroll down to find the links where you can learn more about each hazard model. Example results computed for each of these models can be accessed through the hazard models explorer available in the [[https://platform.openquake.org/explore/| OpenQuake-platform]].
