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.

The resolving power of coseismic surface displacement data for fault slip distribution at depth [PDF]

Geophysical Research Letters, 2003
The spatial slip distribution of the August 17, 1999, Izmit (Turkey) earthquake has previously been determined from both geodetic and seismological data. Though the models derived agree on a broad scale, they are significantly different in detail.

Brittle Creep as a Mechanism for Postseismic Relaxation in Upper Crustal Dolomite Marble

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract In many locations, earthquakes in the upper crust occur in carbonate rocks, whose deformation affects aftershock sequences and postseismic relaxation. We investigate the stress relaxation process and strain evolution in Jinping dolomite marble (porosity <0.2%) subjected to multi‐stage stress ramp‐relaxation cycles under confining pressures of ...

Coherence Difference Analysis of Sentinel-1 SAR Interferogram to Identify Earthquake-Induced Disasters in Urban Areas

Remote Sensing, 2018
This study proposes a workflow that enables the accurate identification of earthquake-induced damage zones by using coherence image pairs of the Sentinel-1 satellite before and after an earthquake event.

A Transient in Surface Motions Dominated by Deep Afterslip Subsequent to a Shallow Supershear Earthquake: The 2018 Mw7.5 Palu Case

Geochemistry, Geophysics, Geosystems, 2021
The 2018 Mw7.5 Palu earthquake is a remarkable strike‐slip event due to its nature as a shallow supershear fault rupture across several segments and a destructive tsunami that followed coseismic deformation. GPS offsets in the wake of the 2018 earthquake

Temperature Dependence of Fault Frictional Healing in Quartz Gouges at Hydrothermal Conditions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Fault healing allows the accumulation of stress along faults during interseismic periods. In this critical stage, temperature‐dependent fluid‐rock interactions within fault zones become crucial at seismogenic depth in controlling fault strength recovery. However, frictional healing at hydrothermal conditions is still underexplored.

Integration of Field Observations With Forward and Inverse Modeling for Tsunami Reconstructions Along the Fjord‐Dominated Coastlines of Northern Cascadia

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Forward and inverse modeling techniques are often applied to paleotsunamis to reconstruct inundation parameters. The accuracy of both types of models can be influenced by geomorphology, particularly in areas such as northern Cascadia, where rocky headlands and fjords influence tsunami flow and the preservation of sedimentary deposits ...
