Coseismic Shallow Slip Deficit Accounted for by Diffuse Off‐Fault Deformation

Geophysical Research Letters
AbstractEarthquake ruptures produce fault slip and kilometer‐wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated. We produce a refined slip model for the 2019 Ridgecrest, California, earthquakes, and analyze the relations between down‐dip rupture process, and surface

CALIBRATION AND VALIDATION OF METHODOLOGY THAT INCORPORATES VARIABILITY IN COSEISMIC SLIP SPATIAL DISTRIBUTION

Coastal Engineering Proceedings, 2020
The main objective of this work is to determine whether is it possible to use the Phase Variation Methodology in an early warning context. For this, it is sought to determine the value of alpha that best reproduces the inundation observed for the Maule event (2010), and that is capable of reproducing the uncertainty that a tsunami prediction process ...

Coseismic and Postseismic Deformations of the 2023 Turkey Earthquake Doublet

Remote Sensing
On 6 February 2023, an earthquake doublet of Mw 7.8 and Mw 7.5 occurred in southeastern Turkey and caused surface ruptures over 350 km for the eastern Anatolian fault (EAF) and 150 km for the Surgu fault (SF), respectively. Over 3700 Mw > 3.0 aftershocks

Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 2. Hellenic Subduction System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract The Hellenic subduction system is the primary locus of Nubia‐Eurasia convergence, yet the distribution of strain accumulation along it is still debated. Here, we invert 832 geodetic velocities and 146 earthquake slip vectors to assess the spatial variability of interseismic locking and provide new constraints on the rate of slip deficit ...

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.

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 ...

Coseismic Deformation Obtained by Various Technical Methods and Its Constraint Ability to Slip Models of Maduo Earthquake

Remote Sensing
The coseismic deformation field on both sides of the fault, especially the distribution and change characteristics of near-field deformation, not only provides important constraints for the fine inversion of the slip distribution model but also serves as

Fault model of the 2017 Jiuzhaigou Mw 6.5 earthquake estimated from coseismic deformation observed using Global Positioning System and Interferometric Synthetic Aperture Radar data

Earth, Planets and Space, 2018
On August 8, 2017, the Jiuzhaigou Mw 6.5 earthquake occurred in Sichuan province, southwestern China, along the eastern margin of the Tibetan Plateau. The epicenter is surrounded by the Minjiang, Huya, and Tazang Faults.
