Abstract

 In this
investigation, we study the tsunami hazard associated with the Ionian- Adriatic
Sea fault system. In spite of the fact that the great majority of seismic
tsunami is generated in ocean domains, smaller basins like the Ionian and
Adriatic Seas sometimes experience this phenomenon. A scenario-based method is
used to provide an estimation of the tsunami hazard in this region for the
first time. Realistic seismic sources, with tsunami potential, are found to
model expected coseismic deformation, which is translated directly to the water
surface and used as an initial condition for the tsunami propagation. The
results from seismicity indicate seven examined sources, only one possesses a
very high threat causing wave amplitudes up to 4 m, one high, two intermediate
and three low causing wave amplitudes smaller than 4 m at some tourist resorts
along the Ionian-Adriatic shoreline.
