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

Reinterpreting the Recurrence Time–Moment Relation of Global Repeating Earthquakes: A Scattered Data Cloud Bounded by Crack‐Model Physics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Repeating earthquakes are recurrent ruptures of the same asperity along creeping faults, and their recurrence time–moment (Tr ${T}_{r}$–M0 ${M}_{0}$) scaling provides key constraints on earthquake physics and fault creep. However, previous studies have reported Tr∝M01/6 ${T}_{r}\,\propto \,{M}_{0}^{1/6}$, seemingly inconsistent with the ...

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 ...

Aftershocks driven by afterslip and fluid pressure sweeping through a fault‐fracture mesh [PDF]

Geophysical Research Letters, 2017
AbstractA variety of physical mechanisms are thought to be responsible for the triggering and spatiotemporal evolution of aftershocks. Here we analyze a vigorous aftershock sequence and postseismic geodetic strain that occurred in the Yuha Desert following the 2010 Mw 7.2 El Mayor‐Cucapah earthquake.

Spatio-temporal evolution of afterslip following the Mw 7.8 Pedernales earthquake, Ecuador

, 2021
International audienceWe use 40 continuous GPS stations in Ecuador to quantify 3 years of the post-seismic deformation that followed the Mw 7.8 April 16 Pedernales earthquake.

Seismic‐afterslip characterization of the 2010 MW 8.8 Maule, Chile, earthquake based on moment tensor inversion

Geophysical Research Letters, 2012
On February 27th 2010, a MW8.8 earthquake struck the coast of south‐central Chile, rupturing ∼500 km along the subduction interface. Here we estimate the amount of seismically‐released afterslip (SRA) and the mechanisms underlying the distribution of ...

Probing time-dependent afterslip and viscoelastic relaxation following the 2015 Mw7.8 Gorkha earthquake based on the 3-D finite-element model

Earth, Planets and Space, 2020
We analyzed daily displacement time series from 34 continuous GPS stations in Nepal and 5 continuous GPS stations in South Tibet, China, and extracted the first 4.8 years of postseismic motion after the 2015 Mw7.8 Gorkha 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.

Evolution of Pore Fluid Pressure in an Accretionary Outer Wedge Over Megathrust Earthquake Cycles: The Northern Cascadia Example

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The evolution of pore fluid pressure ( Pf$P_{\mathrm{f}}$) in the most seaward portion of a subduction accretionary prism plays an essential role in the cycle of tsunamigenic earthquakes. Based on recent geophysical observations, here we propose a testable conceptual model for this evolution for northern Cascadia offshore of Washington.

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).
