Thia monograph provides a systematic catalogue description of all 97 known submarine volcanoes and aeamounts in the Kurile island arc, using materials of the R/V "Vulkanolog" six voyages. Interpretations of their morphostructural features are based on echo sounding, seismic reflection profiling, and characteristics of the magnetic field. Compositions have been determined for 80 of the volcanoes, including petrographic and geochemical data, using dredged material.
During concurrent study of subaerial and submarine volcanoes regularities in their spatial-structural distribution, transverse and longitudinal petrogeochemical, mineral, and isotopic zoning, and xenolith distribution in the lavas have been recognized. Volcanic activity is distributed in the frontal and rear-arc zones. These data are used to develop a model for magma generation with two zones of magma generation related to two levels of volatile separation from the subducting lithospheric plate.

Submarine volcano 7.10, which is part of the North Iturup group of submarine volcanoes of the Kuril island arc, was studied in 5 voyages of the research vessel Vulkanolog in 1982–1989. Comprehensive studies have shown that the edifice of the 7.10 submarine volcano is composed of rocks of a range from dacites to basalts. The summit and slopes of the volcano are devoid of sediments, and the base is overlain by a sedimentary stratum, thickness of which reaches 800 m. The minimum depth recorded above the top of the volcano is 210 m. In the volcanic edifice, subvertical, northeastern and northwestern feeder channels, as well as peripheral magma chambers at depths of 2.5–3.0 km, were identified. It is assumed that during the terminal eruption, small lava flows poured out in the northeast and southwest directions, while the main lava flow poured out in the southeast direction and reached the base of the volcanic edifice.
