The numerical analysis of the evolution of tsunamis is performed for the Sea of Azov. Our calculations are carried out on a grid with steps of 500 m, as applied to seaquakes with magnitudes within the range 6–7 for 18 circular zones of generation covering almost the entire water area of the sea. It is shown that the oscillations of the sea level in the form of cellular waves are formed as a result of the wave reflections from the coasts. Small areas of the elevated activity of waves are formed in the zones of irregularity of the coastline on the north coast of the sea and in the zones of shoals in the southeast part of the basin. On the basis of the determined values of extreme elevations and lowerings of the sea level, we can make a conclusion that the tsunami hazard is quite low for the coast of the Sea of Azov.
