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 structure of South Kamchatka according to geophysical data

Геодинамика и тектонофизика, 2018
Differences have been discovered in the deep structures of North and South Kamchatka, which raises a question about a boundary between these regions. This problem has been studied on the basis of the seismologic, inverse seismic tomographic (P-waves) and

‘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 ...

Cretaceous to Paleocene depositional history of North-Pacific subduction zone: reconstruction from the Nemuro Group, eastern Hokkaido, northern Japan [PDF]

, 2003
The Campanian-Paleocene Nemuro Group comparing the oldest strata in the Kuril Arc, is distributed in the east of Hokkaido Island, northern Japan. Strata of the group in this region are sedimentologically classified into eight depositional facies, most of

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 ...

A High‐Resolution 3‐D P‐Wave Velocity Structure of the South‐Central Cascadia Subduction Zone From Wide‐Angle Shore‐Crossing Seismic Refraction Data

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 2, February 2025.
Abstract This study addresses a significant gap in understanding the features of the south‐central Cascadia subduction zone, a region characterized by complex geologic, tectonic, and seismic transitions both offshore and onshore. Unlike other segments along this margin, this area lacks a 3‐D velocity model to delineate its structural and geological ...

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 ...

Study of the Faults Network of Kunashir Island (Kuril Islands) in Order to Reconstruct the Features of its Tectonic Evolution

Russian Journal of Earth Sciences
The paper is devoted to the study of the faults on Kunashir Island, focusing on their classification, morphology, kinematics, timing, and causes of formation, which are key to understanding the tectonic evolution of the area. The magma-supporting role of
