Landscape structure change of Matua Island in the latter half of the 20th - beginning of the 21st centuries (Kuril Archipelago)

For the first time for the Kuril Islands, we present the results derived from investigating the changes in landscape structure of Matua Island that have been taking place since the latter half of the 20th century under the effect of volcanic activity. We constructed the 1:200 000 landscape maps for different time spans. We consider in detail the issue relating to the development of the geosystems on the island in the wake of the 2009 eruption. A cartographic-statistical analysis of the landscape maps is carried out, and the role of volcanism in the change of the quantitative parameters of landscapes is highlighted.
