Finite fault inversion of DInSAR coseismic displacement of the 2009 L'Aquila earthquake (central Italy) [PDF]

Geophysical Research Letters, 2009
We define the geometric and kinematic characteristics of the fault activated during the Mw = 6.3, 6 April 2009 L'Aquila earthquake, from the modeling of Envisat and COSMO‐SkyMed (the first ever X‐band interferogram inverted for a coseismic dislocation study) DInSAR interferograms.

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.

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 ...

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.

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.

Estimation of the Wenchuan Earthquake Rupture Sequence Utilizing Teleseismic Records and Coseismic Displacements [PDF]

Advances in Civil Engineering, 2018
For the 12 May 2008 Mw 7.9 Wenchuan earthquake, two imbricate faults, Beichuan fault and Pengguan fault, have ruptured simultaneously. Special attention should be paid to the point of 40 km northeast of the epicenter, in which the Xiaoyudong fault intersects the above two faults, creating a complex fault structure.

Role of landslides on the volume balance of the Nepal 2015 earthquake sequence

Scientific Reports, 2021
The 7.8 Mw earthquake that struck Nepal on April 25th, 2015 triggered over 21,000 landslides over an area of more than 25,000 km2. These landslides contributed to mass wasting, partially compensating the tectonic uplift by the earthquake.

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 ...

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.
