Inhomogeneous structure of magnetic layer of the Kuril Island Arc [PDF]

Geodynamics & Tectonophysics, 2020
An innovative technology of anomalous magnetic field inversion was applied to construct 2D models of the magnetic layer using three profiles crossing the southern, central and northern parts of the Kuril Island Arc. In the frontal area of the northern and southern parts, a zone of increased effective magnetization is clearly distinguished.

Chemical weathering fluxes from Paramushir volcanic island (Kuril Island arc, Russia) [PDF]

E3S Web of Conferences, 2019
The rates of the chemical erosion for Paramushir Island, north Kuril Arc, were studied. The rates of the chemical erosion for Paramushir Island, north Kuril Arc, were studied. They were based on the results of the flow rate measurements and chemical analyses of 35 river’s water, sampled in July 2017.

COMPLEX GEOLOGICAL-GEOPHYSICAL STUDIES OF THE UNDERWATER VOLCANO 7.10 (KURIL ISLAND ARC) [PDF]

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2021
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.

TO THE 90th ANNIVERSARY OF THE ERUPTION OF THE TAKETOMI SIDE VOLCANO (ATLASOV ISLAND, KURIL ISLAND ARC)

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2023
The eruption of the unique Taketomi side volcano, located on Atlasov Islandin the northern part of the Kuril island arc, started underwater and ended on land. It happened before people’s eyes and was essentially the formation of a new volcano. The newly formed side volcano was studied by famous Japanese scientists in 1933–1936, and from 1946 to the ...

Submarine Volcano 8.10 (Kuril Island Arc)

Russian Journal of Pacific Geology, 2022
The submarine volcano 8.10, part of the South Iturup group of underwater volcanoes of the Kuril island arc (KIA), was studied using a proven technology of quantitative interpretation of hydromagnetic survey materials in combination with echo sounding, continuous seismoacoustic profiling, and analysis of petromagnetic properties and chemical composition

Underwater gas-hydrothermal activity within the Kuril island arc [PDF]

Geosystems of Transition Zones, 2021
The Kuril island arc is an important element of the Pacific transition zone, within which such modern geological processes as underwater gas-hydrothermal activity occur. The study of underwater gas-hydrothermal activity, which affects the natural environment and all life activities, has not only fundamental but also a great practical importance.

TRANSFORMATION OF GRAVITY ANOMALIES WITHIN LARGE TERRITORIES (BY THE EXAMPLE OF THE KURIL ISLAND ARC)

BULLETIN OF KAMCHATKA REGIONAL ASSOCIATION «EDUCATIONAL-SCIENTIFIC CENTER». EARTH SCIENCES., 2022
An algorithm and a program for transformation of gravity anomalies for large territories are presented. The spherical shape of Earth is taken into account and the geodetic coordinates of measuring points are used. The calculations use the «quasi-ellipsoidal» model of V.V.

Melt, fluids, and fractures beneath Ebeko Volcano (Kuril Islands) revealed by ambient noise attenuation tomography. [PDF]

Sci Rep
The northern part of Paramushir Island (Kuril Arc) is dominated by the NNE-SSW oriented Vernadsky Ridge that hosts the presently active Ebeko Volcano, where phreatomagmatic eruptions coexist with complex hydrothermal activity.

Petrology of the 1952 Eruption and Ancient Lava and Pyroclastic Flows of Krenitsyn Peak Volcano, Onekotan Island, Kuril Arc, Russia

Geosciences
Krenitsyn Peak is one of the two active volcanoes on Onekotan Island (Greater Kuril Ridge). The inaccessibility of the island, along with the volcano being situated within a sizeable (7 km in diameter) and cold (3.7 °C) caldera lake, has led to minimal ...

ALGORITHMIC AND METHODOLOGICAL ASPECTS OF TRANSFORMFTION OF REGIONAL GRAVITY ANOMALIES (ON THE EXAMPLE OF THE KURIL ISLAND ARC)

Bulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences
The technique of transforming gravity anomalies for large areas, which uses geodetic coordinates of field points and takes into account the spherical shape of the Earth, is considered. In order to minimize edge effects, two levels of depths for placing equivalent sources (point masses) are used.
