Seismic Structure Characterizing the Large Shallow Slip Zone of the 17th‐Century Kuril Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract The southern Kuril Trench subduction zone experienced a M9‐class megathrust earthquake in the 17th century, and another is highly probable within the next 30 years. This earthquake likely exhibited large coseismic slip at the shallower plate boundary fault, causing a devastating tsunami, while the deeper plate boundary experienced smaller slip,

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

Геодинамика 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 ...

‘The non‐dormant beast’: Antisemitism in communities of Russian nationalists on Vkontakte

Nations and Nationalism, Volume 31, Issue 2, Page 361-377, April 2025.
Abstract The article explores the specifics of Russian antisemitic discourse of recent years using the example of three nationalist communities on Vkontakte, the most popular Russian social networking site, by means of critical discourse analysis. The main strategies they employ to frame the Jews online are stereotyping Jews as ungrateful and greedy ...

Whole‐Mantle Isotropic and Anisotropic Tomography Beneath Japan and Adjacent Regions

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.
Abstract The Japan Islands and surrounding regions have complex structures and tectonics due to strong interactions of four lithospheric plates, including the subducting Pacific and Philippine Sea slabs beneath the Okhotsk and Amurian plates, which have caused catastrophic interplate and intraplate earthquakes, as well as arc and intraplate volcanoes ...

Characteristics of meiofauna in extreme marine ecosystems: a review [PDF]

, 2017
Extreme marine environments cover more than 50% of the Earth’s surface and offer many opportunities for investigating the biological responses and adaptations of organisms to stressful life conditions. Extreme marine environments are sometimes associated

The 2021 Mw8.1 Kermadec Megathrust Earthquake: An Event Rupturing the Slab‐Mantle Interface With Up‐Dip High‐Frequency Seismic Energy Radiation

Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.
Abstract Megathrust earthquakes often break the slab‐crust interface and radiate high‐frequency seismic waves from the down dip of their coseismic slip. In contrast, we show that the 2021 Mw8.1 Kermadec earthquake deviates from this mode. We resolve the kinematic rupture process of the event by leveraging finite fault inversions and a calibrated tele ...

Double seismic zones and stresses of intermediate depth earthquakes [PDF]

, 1981
Data from Japanese local seismograph networks suggest that the stresses in double seismic zones are in-plate compression for the upper zone and in-plate tension for the lower zone; the stresses do not necessarily appear to be down-dip.

Testing Cloud Adjustment Hypotheses for the Maintenance of Earth's Hemispheric Albedo Symmetry With Natural Experiments

Geophysical Research Letters, Volume 51, Issue 20, 28 October 2024.
Abstract Earth's Northern and Southern Hemispheres reflect essentially equal amounts of sunlight. How—and whether—this hemispheric albedo symmetry is maintained remains a mystery. We decompose Earth's hemispheric albedo symmetry into components associated with the surface, clear‐sky atmosphere, and different cloud types as defined by cloud effective ...

A Review of the Migration of Hydrogen From the Planetary to Basin Scale

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 6, June 2024.
Abstract The occurrence of natural hydrogen and its sources have been reviewed extensively in the literature over the last few years, with current research across both academia and industry focused on assessing the feasibility of utilizing natural hydrogen as an energy resource.
