Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract To understand what governs earthquake size, we investigated the 2021 Mw 7.0 Japan Trench earthquake, which began near a nest of repeating earthquakes. High‐precision hypocenter relocation and P‐waveform correlation show that the mainshock initiated nearly identically to Mw 3.8 repeaters.

, 2023 Non-inertial afterslip has been inferred to occur following large earthquakes. An explanation for this slow slip phenomenon is that coseismically generated stresses induce sliding on parts of a fault surface with velocity-strengthening frictional ...

Large Afterslip with Episodic Slip Acceleration following the Mw 7.8 Perdernales Earthquake, Ecuador
, 2021 International audienceWe analyze continuous GPS measurements along the central Ecuador subduction segment to quantify three years of postseismic deformation that followed the Mw 7.8 April 16 2016 Pedernales earthquake.

Effects of Bulk Poroelasticity on Repeating Earthquake Sequences: Insights From Numerical Modeling
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.Abstract At seismogenic depths, faults and the surrounding rock are saturated with water. Fault slip induces volumetric strains in the bulk, causing compression or dilation of pore fluid, which alters pore pressure—a phenomenon known as the poroelastic effect. This pore pressure change can, in turn, influence fault slip behavior.

Tracking Slow‐Moving Landslide Responses to the 2023 Kahramanmaraş Earthquake With InSAR
Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Strong earthquakes can have a dual impact on the slow‐moving landslide budget of a landscape by either triggering new actively deforming hillslopes or stabilizing existing ones. However, their regional‐scale influence on hillslope processes remains poorly understood because of limited observational coverage and the masking effects of long ...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

SeismicaSurface afterslip can persist over several years, with displacements reaching tens of centimeters. Such deformations can damage structures, making it crucial to understand their temporal changes for effective post-earthquake reconstruction.
