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.

There has been given a new data regarding morphology of submarine volcanic ridges Gidrographov and Browton (Kurile island arc). Within the limits of this ridges there has been discovered four new submarine volcanoes, that has not been included in the Catalogue of «Submarine volcanoes and mountains of Kurile island arc». Two in the Gidrographov ridge and two in the Browton ridge.
