The tsunami impacts in Russia include coastal areas of Kamchatka, the Kuril Islands, Sakhalin Island and Primorye
Climate change could trigger giant, deadly tsunamis from Antarctica, a new study warns. Sediment shifting beneath the Antarctic seabed could trigger giant tsunamis due to rising ocean temperatures. Fourteen cities and dozens of towns in Russia are vulnerable to tsunamis across three regions of the Far East, with powerful waves capable of hitting their coasts at speeds of up to 1,000 kilometres per hour.
