Numerical modeling of generation and propagation of tsunami waves caused by underwater earthquakes in the Black Sea basin is carried out using the model of dynamic seismic source. A number of historical tsunamis are considered as well as possible catastrophic tsunami with large magnitudes from the sources whose location is close to the historical events considered here. The process of tsunami source formation and propagation of tsunami waves in the entire basin of the sea up to 10-meter isobath was considered. Kinematic vertical motion of key-blocks, into which the source of the earthquake is divided, was used to model the seismic source. The obtained results were compared with the data of pressure gauges and results of other authors. The distribution of maximal heights of tsunami waves along the entire Russian coast of the Black Sea was obtained for each calculation. Pressure gauge records were plotted for a number of points at the eastern coast located close to eight Russian cities such as Anapa, where the probability of earthquakes and tsunami is high in the nearest future.
