ИСТИНА

According to the results of the interpretation of satellite images and field observations, modern dynamics of the accumulative coast of the Sea of Okhotsk composed of the sandstone of the Okhotsk Sea in the area of the Vetrovoy Bridge at Iturup Island of the Great Kuril Ridge were studied. The islands of the Great Kuril Ridge are characterized by active modern geological processes. They are expressed in high-amplitude movements of the earth’s surface along faults, intense volcanism, increased seismicity and high rates of coastal processes. The islands are also interesting in practical terms in connection with deposits of various minerals, including industrial reserves of magnetite sand, as well as the development of recreational and educational tourism. Therefore, they have been well-studied previously. However, many aspects of the island’s landscapes evolution are still unclear. This applies in particular to coastal morphosystems. Studying the dynamics of sea coasts in different climatic and geodynamic conditions makes it possible to gain new knowledge about the processes of interaction between land and sea. It is also closely related to geoecological issues, provides an opportunity for a reasonable approach to the solution of important economic problems.
