We perform the numerical analysis of the process of propagation of long waves in the northwest part of the Black Sea and consider ten possible zones of the seismic generation of tsunamis. The numerical analysis is performed on a grid with steps of 500 m. It is shown that the location of the tsunami source significantly affects the distribution of the heights of waves along the coast. As a rule, the most intense waves are formed in the closest part of the coast. The earthquakes in the South-Coast seismic zone do not lead to the formation of tsunamis in the west part of the sea. Only strong earthquakes in the northwest part of the sea can be responsible for noticeable oscillations of the Black-Sea level. The period of tsunamis near Odessa is close to 1 h and depends on the magnitude of the earthquake. In the region of Sevastopol, this period is 2--3 times smaller. In the major part of the coastal points, the extreme elevations and lowerings of the sea level do not exceed (in modulus) the initial displacements of the sea surface at the source of tsunamis. An intensification of waves emitted from the zones of generation located in the deeper part of the investigated region was observed for some parts of the Romanian coast and the west coast of Crimea. As the magnitude of the earthquake increases, the intensification of waves near the coast becomes more pronounced.
