The Sea of Azov is also famous for its seiches. It is unlikely that this word will mean anything to a person far from hydrology. Nevertheless, every vacationer who finds himself on the shore of the Sea of Azov should know about this phenomenon. Translated from the language of science into human, seiches are standing waves that form in closed bodies of water. Most often, they are caused by gusts of wind, changes in atmospheric pressure or seismic tremors. Having suddenly appeared, such a wave literally stands, reflecting off the walls of the reservoir. The lifetime of a standing wave usually ranges from a couple of minutes to several days, it rises in height from a dozen millimeters to two or three meters. It turns out that a global geological fault runs along the bottom of the Sea of Azov at a depth of about one kilometer. It creates seismic activity that generates standing waves. The overlapping of bottom layers causes the formation of underwater rivers, which are extremely dangerous for humans. This is especially true for windsurfing enthusiasts and those who don't mind swimming at the end of the Azov spits, since when seiche vibrations are amplified by a storm surge or increased river runoff, a sharp rise or fall of water in the sea can occur, and sometimes even a small tsunami can form! A similar danger awaits vacationers on the Berdyansk, Fedotov, Dolgaya, Yeisk and Obitochny spits. For example, on the Dolgaya spit, which juts out into the sea for 14 km, a terrible flood occurred in 1983. Fishermen's houses were torn off the ground with terrible force and washed away into the sea. They were later discovered on the other bank, in the Ukrainian SSR. A similar story happened in 2006.
