Scenarios and Tsunami Hazard Assessment of Tectonic Origin in the Ionian-Adriatic Seas

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.
