Melt Architecture Under East Asian Volcanoes Revealed by Anisotropic Tomography

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Cenozoic volcanic rocks in East Asia are widespread across subduction zones, oceanic plates, and continental interiors. The generation of these volcanic materials is closely associated with partial melting of the upper mantle and the stagnation of the Pacific slab in the mantle transition zone.

INTEGRATED GEOLOGIC-GEOPHYSICAL INVESTIGATION OF THE RATMANOV SUBMARINE VOLCANIC MASSIF (KURILE ISLAND ARC) [PDF]

open access: yesBulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences, 2020
The article presents the results of integrated geologic-geophysical investigation of the Ratmanov submarine volcanic massif, located in the Kurile Island Arc, 15 km southeast of the Chirinkotan island. There is a small submarine volcano on the northwestern slope of the massif with a relative height of 400–450 m, dredging of which raised andesites and a

Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Cold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much of the faunal diversity remains undocumented.

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

Volcanic-glacial interactions: GIS applications to the assessment of lahar hazards (case study of Kamchatka)

open access: yesЛëд и снег, 2015
On the Kamchatka peninsula, lahars or volcanogenic mudflows arise as a result of intensive snow melting caused by incandescent material ejected by volcanoes onto the surface.

Deep-focus earthquakes: spatial patterns, possible causes and geodynamic consequences

open access: yesГеодинамика и тектонофизика, 2018
The spatial analysis was conducted to analyze the positions of earthquakes hypocenters in the transit zone of the upper mantle and the focal mechanisms of the strongest earthquakes in the subduction slabs of theOkhotskSeasegment of the Kuril-Kamchatka ...

Seismicity to the South of the Louisville Ridge‐Tonga Trench Collision Zone: New Insight Into Processes Controlling Seismic Gaps and Subduction Erosion

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The Louisville seismic gap associated with the subduction of the Louisville Ridge (LR) along the Tonga‐Kermadec trench is a globally prominent feature. Due to the lack of near‐field seismic monitoring, the earthquake potential and seismic behavior in this region have long been an enigma.

Identification of the Atmospheric Vortex Shedding Behind the Jeju Island Based on MODIS and ERA5 Data

open access: yesEarth and Space Science, Volume 12, Issue 5, May 2025.
Abstract A fascinating phenomenon often occurs as pairs of vortices in two rows on the leeward of some islands. The satellite remote sensing has been a major facilitator to observe this phenomenon. In this study, we conduct a statistical analysis on the occurrence of vortex street by processing 20‐year cloud images from the MODIS remote sensing data ...
