Deep-earth geodynamics and metallogenic peculiarities in the Kunashir-Urup chain of the Kuril Islands

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2019
The southern part of the Kuril island-arc system (from Kunashir to Urup islands) differs from the northern part (from Simushir to Paramushir islands) in its spatial arrangement relative to the subducting Pacific megaplate’s motion vector, greater number ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

open access: yesSedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

A new “Sardine Era”: results of researches and fishe- ry in the first decade

open access: yesИзвестия ТИНРО
Japanese sardine stock assessments in the North-West Pacific are overviewed for the past 10 years on the data of research surveys by midwater trawls in the area at the Pacific side of Kuril Islands in 2014–2024 and fishery statistics. The feeding schools

Intra-annual variability of the mixed layer parameters in the Okhotsk Sea

open access: yesИзвестия ТИНРО, 2018
All available oceanographic data for the deep-water part of the Okhotsk Sea, in total 111,944 stations collected in 1931–2014, are analyzed after removing the duplicate and lowquality ones.

New Terrestrial Native Iron Discovered on Earth's Surface

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity. To date, native iron has mainly been found in basalts, ophiolites, and deep hydrothermal systems.

Generalized assessments of composition, quantitative distribution and biomass of benthic macrofauna on the shelf and slope in the North-West Pacific

open access: yesИзвестия ТИНРО, 2015
Quantitative information on the bottom macrofauna of the continental shelf and slope down to the depth 2025 m is generalized for the Far East of Russia and the adjacent waters of North Korea and Japan (in total 32,700 bottom trawls obtained in 224 ...

How the 29 July 2025 M8.8 Kamchatka Earthquake Shook the Ionosphere Over Japan

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract This study investigates the mid‐field (∼1,100–3,800 km) ionospheric response to the 29 July 2025 Kamchatka earthquake over Japan using multi‐instrument observations, raytracing, and numerical simulations. Total electron content (TEC) observations from GPS satellite G04 and Galileo satellite E10 show a maximum TEC perturbation of ∼0.5–0.85 TECU

Profundum solomoni (Amphipoda: Uristidae) Exhibits a Disjunct Geographic Distribution at Hadal Depths Across the San Cristobal Trench, Santa Cruz Trench and Nova Canton Trough

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 639-651, July 2026.
ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

Itinerary of Expedition to the Southern Kuril Islands (2009–2012) [PDF]

open access: yes, 2014
Expedition to the southern Kuril Islands was conducted for the purpose to estimate present condition of fauna and flora of these islands. In 2009–2012, we visited Shikotan (2010),Kunashiri (2009, 2012) and Etorofu (2012) Islands under the arrangement of ...
