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

The 1886 Charleston, South Carolina, Earthquake: Relic Railroad Offset Reveals Rupture

The Seismic Record, 2023
In the absence of documented surface rupture during the 1 September 1886 Charleston earthquake, there has been considerable speculation about the location and mechanism of the causative fault.

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 ...

Oblique Blind Faulting Underneath the Luzon Volcanic Arc During the 2022 Mw 7.0 Abra Earthquake, the Philippines

Geophysical Research Letters, 2023
Unknown seismogenic structures lurking beneath convergent margins introduce substantial uncertainty in seismic hazard assessments. In northwestern Luzon, the Mw 7.0 Abra earthquake on 27 July 2022 highlights the seismic activity along an unmapped blind ...

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 ...

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Shallow segment rupture associated with the 2025 Kamchatka earthquake inferred from ALOS-2/PALSAR-2 InSAR

Earth, Planets and Space
We detected coseismic deformation associated with the 2025 Kamchatka earthquake using the Advanced Land Observing Satellite-2 (ALOS-2) ScanSAR (wide-swath) data. The coseismic deformation revealed predominantly greater than 1.5 m of eastward displacement,

Estimating Off‐Fault Deformation Using Convolutional Neural Networks Trained on Experimental Strike‐Slip Faults

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Scaled physical experiments using crustal analog materials can simulate off‐fault deformation near strike‐slip faults and provide direct observations of deformation partitioning during strike‐slip fault evolution. Using experimental fault maps and off‐fault deformation labels, we trained and tested four 2D Convolutional Neural Networks (CNNs ...

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.
