NUMERICAL MODELING OF THE PROPAGATION AND STRENGTHENING
OF TSUNAMI WAVES NEAR THE CRIMEAN PENINSULA AND
THE NORTHEAST COAST OF THE BLACK SEA

The linear model of long waves is used for the evaluation of the parameters of tsunami waves along the
South Coast of Crimea, in the near-Kerch zone, and near the northeast coast of the Black Sea. Our nu-
merical investigations are carried out for 24 probable locations of the elliptic zones of tsunami genera-
tion over the continental slope of the basin. The amplitude characteristics of tsunamis are computed for
27 sites of the Black-Sea coast. It is shown that significant strengthening of tsunami waves is possible in
the course of their propagation toward the coast. The highest waves are formed at the sites of the coast
closest to the seismic source. The dependence of the intensity of tsunami waves along the Black-Sea
coast on the location of the seismic source and its magnitude is analyzed.
According to the estimates of different authors, about 20–22 events of abnormal oscillations of the sea level
recorded in the Black Sea can be regarded as tsunami waves [1–6]. According to these data, the events of tsu-
namis caused by the earth- and seaquakes were observed at different times almost along the entire sea coast.
Only for the four major earthquakes of the last century, tsunamis were recorded by marigraphs at several sites of
the Crimean and Caucasian parts of the sea coast [6–10]. All these events were not connected with serious haz-
ards for the cities and villages and the objects of economic activity in the coastal zone because the wave heights
at the sites of measurements did not exceed
m. However, the conclusion that strong tsunamis never appear
in the Black Sea should be regarded as erroneous. Indeed, the available historical data demonstrate that abnor-
mal variations of the sea level near Sukhumi (20 AD), Sevastopol (103), Varna (543), Bosporus Strait (557),
Evpatoriya (1341), Foros (1427), in the north part of Turkey (1598), and near the east coast of the Black Sea
(1909) were accompanied by the waves with heights of up to
m [1, 2] and, in most cases, had catastrophic
consequences for the inhabitants and economic objects of the coastal regions.
The interest to a more comprehensive investigation of tsunamis in the Black Sea became much stronger for
the several last years in connection with the plans of creation of the regional system of early warning about
Black-Sea tsunamis as a constituent part of the All-European system of observations. In June 2005, at the 23rd
Session of the UNESCO Intergovernmental Oceanographic Commission in Paris, a decision was made to form
the Intergovernmental coordination group on the creation of a system of tsunami early warning and mitigation in
the Northeast Atlantic, Mediterranean and Connected Sea (ICG/NEAMTWS). The Black Sea was also included
in the sphere of interests of this group .
