| Abstract: | We calculated the expected impact on the Italian coast of the Adriatic Sea of a large set
of tsunamis resulting from potential earthquakes generated by major fault zones. Our approach
merges updated knowledge on the regional tectonics and scenario-like calculations of expected
tsunami impact.
We selected six elongated potential source zones. For each of them we determined a Maximum
Credible Earthquake and the associated Typical Fault, described by its size, geometry and
kinematics. We then let the Typical Fault float along strike of its parent source zone and simulated
all tsunamis it could trigger. Simulations are based on the solution of the nonlinear shallow water
equations through a finite-difference technique. For each run we calculated the wave fields at
specified simulation times and the Maximum Water Elevation field, then generated travel-time
maps and maximum wave-height profiles along the target coastline. Maxima were also classified in
a three-level code of expected tsunami threat.
We found that the southern portion of Apulia facing Albania and the Gargano promontory are
especially prone to the tsunami threat. We also found that some bathymetric features are crucial in
determining the focalization-defocalization of tsunami energy. We suggest that our results be taken
into account in the design of early-warning strategies. |
