Mainshock‐Induced Stress Changes Modulate Initial Aftershocks on Complex Branching Faults of the 2019 Ridgecrest Earthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Large earthquakes can activate complex aftershock fault networks. In such systems, what controls the spatiotemporal evolution of early aftershocks remains a critical yet unresolved problem. Here, using the 2019 M 7.1 Ridgecrest earthquake as an example, we partition the first 10 days of aftershocks onto 15 branching faults activated by the ...

Permanent Hydraulic and Poroelastic Property Changes in a Deep Aquifer Triggered by the Distant Tohoku Earthquake

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract While large earthquakes can alter groundwater systems far from the epicenter, their hydromechanical changes remain elusive. We investigate the 2011 Mw 9.0 Tohoku earthquake's impact on a deep well‐aquifer system ∼2,000 km from the epicenter. By employing the groundwater tidal and barometric pressure response methods, we perform tidal response ...

Hydro‐Mechanical Controls on Swarm Recurrence on the Westernmost Gofar Transform Fault, East Pacific Rise

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Coseismic and Postseismic Slip Analysis of the 2024 Mw 7.0 Wushi Earthquake: Insights From InSAR Observations and Slip Inversion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Analysis of fault slip behavior is crucial for assessing regional seismic hazards. This study employs Sentinel-1 SAR data to investigate the coseismic and postseismic deformation associated with the 2024 Mw 7.0 Wushi earthquake using Interferometric ...

GNSS VELOCITY AND STRAIN FIELD IN THE NORTHERN SUMATRA 15 YEARS AFTER THE 2004 M9.2 SUMATRA ANDAMAN EARTHQUAKE

Геодинамика и тектонофизика
The 2004 M9.2 Sumatra-Andaman earthquake in the tectonically active northern Sumatra, could generate postseismic deformation up to a recent period and needs to be considered for earthquake potential study.
