Forming peculiarities and manifestation of tectonic faults in soft rocks [PDF]

, 2012
Features of distribution of tectonic structures in soft rocks confirm the presence of horizontal tectonic forces in the formation of faults and are based on the manifestation of their morphological features.

Observing Broadband Tsunamis in Deep Water Via Distributed Acoustic Sensing

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Tsunamis have been detected as strain variations in optical fibers of submarine cables through distributed acoustic sensing (DAS). However, the usefulness of strain variations during tsunamis for early warning remains unclear. Here, we compare fiber strains and sea‐level changes for both infragravity waves in ambient noise and tsunamis ...

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Low‐Frequency Ocean Waves Triggered by Tropical Cyclones via Seafloor Distributed Acoustic Sensing

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Propagation of low‐frequency ocean waves, including infragravity (IG) and internal waves, affect ocean dynamics and energy transfer within marine environments. IG waves are long‐period ocean surface waves that can propagate long distances across the ocean and impact the coastlines and deep ocean, while internal waves are buoyancy‐driven ...

Synthesis of the Laboratory Frictional Properties of a Major Shallow Subduction Zone: The Nankai Trough, Offshore SW Japan

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Nankai Trough has a long history of ≥Mw 8 earthquakes and associated tsunamis. It has been the focus of decades of research, including drilling, providing the opportunity to measure the laboratory frictional properties of shallow accretionary prism samples. We collate all available friction data from the Nankai Trough and correlate it with
