Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand

Basin Research, Volume 38, Issue 5, September‐October 2026.
Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Cascadia Slow Earthquake Behaviors Modulated by Tectonic and Environmental Forcings

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear. Previous studies suggest that annual hydrological cycle dominates the tremor seasonal behavior in northern Cascadia.

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Detecting sub-instability before three Mw > 6.0 earthquakes on Chinese mainland in 2020–2022 with load/unload response ratio

Geomatics, Natural Hazards & Risk
The sub-instability refers to a stress state that exists between the maximum stress the rock can withstand and its final failure. This stress state should be an indicator of impending large earthquakes, as it occurs in the final stage of earthquake ...

Internal Structure and Formation Process of a Giant East Antarctic Grounding‐Zone Wedge

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The marine‐based portions of the East Antarctic Ice Sheet are currently losing mass at an accelerating rate due to atmospheric and oceanic forcing. Assessing these changes requires understanding long‐term grounding‐zone dynamics preserved in glacial geomorphology, including understudied East Antarctic shelf sectors.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Latitude-Time Total Electron Content Anomalies as Precursors to Japan's Large Earthquakes Associated with Principal Component Analysis

International Journal of Geophysics, 2011
The goal of this study is to determine whether principal component analysis (PCA) can be used to process latitude-time ionospheric TEC data on a monthly basis to identify earthquake associated TEC anomalies.

Foreshocks of the 2016 MS5.1 Yunlong earthquake in Western Yunnan, China, and implications for earthquake nucleationKey points

Earthquake Science
Monitoring the evolution of foreshocks can be a valuable way to analyze the nucleation process. Foreshocks accompanying moderate mainshocks have been recorded in the west of Yunnan Province, China.

Spatiotemporal Variations of In Situ Vp/Vs Ratios During the 2019 Ridgecrest Earthquake Sequence Suggest Fault Zone Condition Changes

Geophysical Research Letters
The 2019 Mw 7.1 Ridgecrest earthquake was the largest event in California over the past 20 years. The earthquake was preceded by a sequence of foreshocks. However, the physical processes leading to the mainshock remain unclear.
