[en] The far east coast of the USSR is subjected to the effects of tsunamis generated closely in the Kuril-Kamchatka trench and the sea of Japan, and distantly in the Pacific. The Tsunami Warning Services were organized in Sakhalinsk and Kamchatsk regions in 1956. In 1983 service was set up in the Primorsky Krai area. The Warning Services use 6 seismic and 53 tide stations. The principal method of tsunami prediction is seismic based on the registration of earthquake waves preceding the tsunami wave, by determining earthquake magnitude epicenter and tsunami generation probability based on these parameters. Sea level observations are of secondary importance but are used in the forecasting of waves far from the source. These are the main deficiencies of conventional warning services that must be eliminated, and to apply up-to-date informational technology as the basis for UATWS creation. 9 refs, 3 figs, 1 tab
