Grain Size and Fluid Effects on the Frictional Behavior of Simulated Carbonate Fault Gouge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Carbonate rocks exhibit a span of clast and grain size in fault zones. However, the effect of grain size distribution on the frictional behavior of carbonate faults and its implications for natural and induced seismicity remain poorly understood.

Lesser Antilles seismotectonic zoning model for seismic hazard assessment [PDF]

Natural Hazards and Earth System Sciences
Subduction zones pose a considerable challenge within the realm of seismotectonics, owing to their fault and structure interactions. The Lesser Antilles arc is a good example of how these complexities impact seismic hazard studies with strong along ...

Present-day crustal deformation in central Sumatra, Indonesia derived from GNSS observation and tectonic implications

Geodesy and Geodynamics
Central Sumatra, Indonesia, is historically known for its significant seismic activities, most notably the devastating 1883 earthquake. In this study, we measured the interseismic deformation using continuous GNSS observation data for three years from ...

Megathrust Earthquake Potential of the Manila Subduction Systems Revealed by the Radial Component of Seismic Moment Tensors Mrr

Terrestrial, Atmospheric and Oceanic Sciences, 2015
We undertook an investigation of the seismic behavior of large earthquake and estimated the crustal deformation state in the northern Philippine area in terms of the radial component of seismic moment tensors (Mrr) distribution.

Surface creep rate distribution along the Philippine fault, Leyte Island, and possible repeating of M w ~ 6.5 earthquakes on an isolated locked patch

Earth, Planets and Space, 2019
Active faults commonly repeat cycles of sudden rupture and subsequent silence of hundreds to tens of thousands of years, but some parts of mature faults exhibit continuous creep accompanied by many small earthquakes. Discovery and detailed examination of

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters
Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador.

Strain Partitioning, Interseismic Coupling, and Shallow Creep Along the Ganzi‐Yushu Fault From Sentinel‐1 InSAR Data

Geophysical Research Letters
The Ganzi‐Yushu fault (GYF) is one of the most seismically active fault systems in eastern Tibet, having experienced five M > 7.0 earthquakes over the past 300 years.

Geodetic plate coupling and seismic potential on the main Himalayan thrust in Nepal

Earth, Planets and Space
We model interseismic plate coupling distribution on the Main Himalayan Thrust (MHT) in Nepal through the inversion of secular GNSS velocity data. To complement previously published data, we compile velocity data from ten additional continuous stations ...

Modeling the 2023 Türkiye Earthquakes and Strain Accumulation Along the East Anatolian Fault Zone: Insights from InSAR, GNSS, and Small-Magnitude Seismicity, with Implications for the Seismic Potential at Rupture Terminations

Remote Sensing
The 6 February 2023 MW 7.8 and MW 7.6 earthquakes in southeastern Türkiye ruptured more than 400 km of the East Anatolian Fault Zone (EAFZ), producing one of the most destructive seismic sequences in recent history.
