This recipe illustrates the Probabilistic Tsunami Forecasting (PTF), an application of the ingredients more commonly used for long-term PTHA to the case of tsunami warning. This PTF recipe regards tsunamis generated by earthquake sources, which are characterised through both fault and earthquake catalogues. Source probabilities are finally combined with the output of numerical tsunami simulations. PTF output is the probability distribution of tsunami intensity at given forecast points.

摘要

This recipe illustrates the Probabilistic Tsunami Forecasting (PTF), an application of the ingredients more commonly used for long-term PTHA to the case of tsunami warning. This PTF recipe regards tsunamis generated by earthquake sources, which are characterised through both fault and earthquake catalogues. Source probabilities are finally combined with the output of numerical tsunami simulations. PTF output is the probability distribution of tsunami intensity at given forecast points.
