A proper implementation of this model requires major changes to the hazard component of the OpenQuake-engine. These improvements will be added in 2015.</color> | + | <color red/white>The GEM hazard team is currently working in close collaboration with NIED scientists at the implementation of the 2012 (Model 2) PSHA Model for Japan.
