term computations) have been carried out, the results at the points of interest
have to be obtained also for very unrealistic/noised input time series. This is
important because when applying the model in real time the system should
work also using truncated input time series: when a tsunami is detected
by the tidal gauges, the tsunamis early warning system immediately has to
forecast the wave properties at the target points. It is unrealistic, given the
limited time available for spreading the warning, to wait until the tsunamis
have been completely measured. It is therefore clear that as the tsunamis
are measured, the available time series is to be used as input data.
The Stromboli tsunami simulation presented is here used to show the
ability of the model to predict the water surface elevation at target points
(i.e. points 2, 3 and 4), as the data become available at a gauge close to
