Abstract
The Propagation Database is a collection of tsunami propagation model runs that have been precomputed for tsunami source functions at selected locations along known and potential earthquake zones.
These pre-computed events can be combined linearly to simulate arbitrary earthquake scenarios to provide a very fast forecast during an actual tsunami event. The accuracy of the Propagation Database has been validated with data from seventeen tsunamis, eight of which were assessed in real-time during events.
The Propagation Database is a key component of the operational tsunami forecasting system (known as SIFT) that the NCTR is developing for deployment at the Pacific and Alaska/west Coast tsunami warning centers. Figure 1 shows the distribution of pre-computed model runs for simulated earthquake sources in the Pacific, Atlantic and Indian oceans.
