The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Transient Creep on the Yarlung Zangbo Suture in Southern Tibet Triggered by the 2015 Gorkha (Nepal) Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.

Source of the 2019 Mw6.9 Banten Intraslab earthquake modelled with GPS data inversion

Geodesy and Geodynamics, 2021
The 2019 MW6.9 Banten Intraslab earthquake occurred at ∼100 km to the northeast of the Sunda Trench with two nodal plane models estimated by the Global Centroid-Moment-Tensor (GCMT) Project with a strike of 200° and a dip of 65°.Continuous GPS data from ...

Evolution of Coupled Seismic‐Aseismic Slip During the 2025 Mw 6.8 Sanriku‐Oki, Japan, Megathrust Sequence

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 9 November 2025, a Mw 6.8 Sanriku‐Oki earthquake struck a Japan Trench segment with inferred recurrent aseismic slip and Mw ∼7 earthquakes. Using S‐net seafloor data, we examine the preparatory and post‐mainshock evolution of this foreshock–mainshock–aftershock sequence.

Cascading Rupture of a Conjugate Oblique Faulting Rift in the 2025 Dingri Southern Tibetan Plateau Earthquake: A Typical Slow‐to‐Fast Process

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The 2025 Mw7.1 Dingri earthquake is the largest normal‐faulting event in southern Tibetan plateau recorded with near‐field observations. By integrating back‐projection imaging, multi‐point‐source inversion, and finite‐fault modeling, we reveal that the rupture propagated at variable speeds in a cascading manner across a complex conjugate fault

Inversion of synthetic geodetic data for the 1997 Colfiorito events: clues on the effects of layering, assessment of model parameter PDFs, and model selection criteria

Annals of Geophysics, 2008
The 1997 September-October Umbria-Marche sequence has been extensively studied in the past by analyzing coseismic displacement data (GPS, leveling, SAR). Here we focus on synthetic data representative of the main event of the 1997 Umbria-Marche

Does Three‐Dimensional Structure Affect Tsunami Excitation and Stress Drop Estimates?—The Case of the 2011 Tohoku Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Reliable calculations of coseismic sea‐surface deformation and stress drop are essential for understanding megathrust earthquake rupture and tsunami behavior. However, the impacts of realistic three‐dimensional (3D) structure, such as seafloor topography and structural heterogeneity, on stress‐change calculations and tsunami excitation during ...

Effects of Pore Fluid Properties on Dynamic Slip in Sandstone‐Derived Fault Gouges From the Groningen Gas Reservoir

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

Improved SAR Amplitude Image Offset Measurements for Deriving Three-Dimensional Coseismic Displacements [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
Offsets of synthetic aperture radar (SAR) images have played an important role in deriving complete three-dimensional (3-D) surface displacement fields in geoscientific applications. However, offset maps often suffer from multiple outliers and patch-like artifacts, because the standard offset-measurement method is a regular moving-window operation that

Fifty Years of Shore Platform Erosion Monitoring at Kaikōura Peninsula, South Island, Aotearoa‐New Zealand

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.
