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.

Mechanics of coseismic and postseismic acceleration of active landslides
Communications Earth & Environment, 2023 Active slow-moving landslides exhibit very different coseismic and postseismic behaviour. Whereas some landslides do not show any postseismic acceleration, there are many that experience an increased motion in the days to weeks following an earthquake ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract We investigate the role of the elasticity and density of the forearc mantle wedge corner on the stress distribution in the forearc region of subduction zones, using numerical quasi‐2D lithospheric deformation models for the Cascadia, Nankai, NE Japan, and Costa Rica subduction zones. We incorporate the forearc mantle wedge corner as an elastic

Frontiers in Earth Science, 2021 Evaluating the transfer of stresses from megathrust earthquakes to adjacent segments is fundamental to assess seismic hazard. Here, we use a 3D forward model as well as GPS and seismic data to investigate the transient deformation and Coulomb Failure ...

Geomorphic Imprints of Coseismic Uplift: Knickpoints and Landslides on the Noto Peninsula, Japan
Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.River knickpoints and slow‐moving landslides show complementary spatial relationships with the vertical and horizontal deformation fields of the 2024 Mw 7.5 Noto Peninsula earthquake. Together, their distributions provide geomorphic information for evaluating cumulative landscape adjustment to repeated coseismic uplift at a regional scale.

Remote Sensing, 2022 On 22 July 2020, an Mw 6.3 earthquake occurred in Nima County, central Qinghai-Tibet Plateau, China. We used the synthetic aperture radar interferometry (InSAR) technique with Sentinel-1 images to retrieve the line of sight (LOS) coseismic deformation ...

Automatic GNSS Coordinate Time Series Analysis for Very Large Networks
Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract We present a new algorithm, AutoCF, for automatically constructing coordinate functions (CFs) for continuously operating GNSS reference stations (CORSs). The iterative algorithm alternates between application of LASSO and Ridge Regression methods, with hyperparameters successively tightened with each iteration to more judiciously scrutinize ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Volcano deformation data provide important constraints on magma dynamics during volcanic unrest and eruptions. From these observations, we can estimate subsurface pressure changes and relate them to volume change in the reservoir. However, because magma and rock are compressible, this volume change cannot be directly equated with eruptive ...

Geophysical Research Letters, 2022 We used the 250‐day postseismic displacements derived from Global Positioning System data to explore various postseismic deformation processes of the 14 April 2010 Mw 6.9 Yushu earthquake, including the afterslip of the fault, viscoelastic relaxation in ...

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.
