Resumo
For the first time, paleoseismological studies have been carried out on Iturup Island to search for vertical coseismic deformations associated with the strongest earthquakes in the southern segment of the Kurilo-Kamchatka subduction zone. Traces of six earthquakes with an average between-event interval of about 330 years have been identified. The last earthquake that caused the coseismic subsidence of the island probably occurred on November 6, 1958.
