Tsunami methodology and result overview

This report gives a brief overview of the tsunami hazard component of the 2015 Global Assessment Report, involving a global hazard analysis. The work presented is the first global scale probabilistic assessment of tsunami hazard. The publication details the applied methodology and input parameters.

The results of this assessment are tsunami inundation footprints for a suite of earthquake events, each with an associated probability of occurence. The results are then used by the International Centre for Numerical Methods in Engineering (CIMNE) to undertake a probabilistic tsunami risk assessment. Among others, the results reveal that the predicted Probably Maximum Losses (PML) for a return period of 500 years for Japan, closely corresponds to the losses due to the 2011 Tohoku earthquake and tsunami.
