The tsunami phenomenon is mainly detected in oceanic domains but it can also occur in small basins as the Adriatic Sea. The presence of great waves has been recorded a few times in the past centuries on the Adriatic shorelines, therefore this suggests the idea to evaluate which could be the maximum amplitude reached by a possible future tsunami event. In this framework we calculate several synthetic mareograms applying to the shallow water basin case both the theory of modal summation, for off-shore sources, and the theory of the Green’s function, for inland sources. Both kinds of tsunamigenic events did already occur in the Adriatic domain, as witnessed in many catalogues. We calculate synthetic mareograms varying those parameters which are the most influencing in tsunami generation in order to estimate the expected values of tsunami maximum amplitude and arrival time, in the whole Adriatic basin, for the selected scenarios.
