Abstract
Although a rare phenomenon, tsunamis in the Black Sea were generated in the past, studies showing more than twenty events observed ( Altinok Y., 1999 ). Earthquakes monitoring in the Black Sea as well as a database with tsunami modeling Scenarios could lead to a better understanding of such phenomena.
A set of 6 past earthquakes were taken into consideration for generating tsunami modeling Scenarios, using the earthquakes Depth, Latitude and Longitude as initial conditions. For preset parameters of fault dimensions and plane solution (Strike, Dip, Rake, Width, Length) a set of 36 different tsunami modeling Scenarios have been run, varying the Magnitude (Mw = 7, 7.5 and 8). These tests using the Tsunami Analysis Tool (TAT) software for modeling tsunamis in the Black Sea resulted in moderate to high tsunami waves, with the highest waves of 3.2 m, for an earthquake with M = 8 in Novorossisk area, generated at 15 km depth. Some of the Scenarios did not generate tsunami waves at all, for a Magnitude of 7 or 7.5.
The computations in this study need more thoroughness, in order to have a better correlation of the results from the tsunami modeling Scenarios and the tsunamis observed in the past.
