Multi‐Scale Rate‐ and Roughness‐Dependent Frictional Constitutive Law and Dynamic Earthquake Sequence Simulation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract The physical mechanisms that govern the multi‐scale source properties of earthquakes, such as fracture energy scaling, where the dynamic energy dissipation of earthquakes scales with fault slip, remain debatable. We introduced the rate‐ and roughness‐dependent friction (RRF) law which accounts for the multi‐scale roughness evolution of the ...

Shallow coseismic slip and downdip afterslip associated with the 2022 MW6.7 Menyuan (China) earthquake

Geodesy and Geodynamics
Investigating the spatial distribution of coseismic rupture, postseismic afterslip, and their interactions is essential for understanding the heterogeneous frictional characteristics of faults, and seismic hazard assessments.

Does Geocentric Sea‐Level Rise in the Maritime Continent Reveal a Tectonic Fingerprint?

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The islands of the Maritime Continent are highly vulnerable to sea‐level rise driven by barystatic, sterodynamic, and vertical land motion (VLM) processes. While tectonics is known to affect relative sea‐level through VLM, its influence on long‐term geocentric sea level (GSL) through crustal deformation and gravity field perturbations remains ...

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Afterslip and slow slip events in the postseismic deformation of the 2016 Pedernales earthquake, Ecuador

, 2020
International audienceIn subduction zones, slip along the plate interface occurs in various modes including earthquakes, steady slip, and transient accelerated aseismic slip during either Slow Slip Events (SSE) or afterslip.

Significant afterslip contribution to postseismic deformation in Sado Island following the 2024 Noto Peninsula earthquake: insights from two dense GNSS observation networks

Earth, Planets and Space
This study investigated postseismic deformation resulting from the 2024 Noto Peninsula earthquake on January 1. Particular focus was placed on the displacement observed in Sado Island, which is located several tens of kilometers east of the eastern end ...

Rheological and tectonic implications of eastern Tibet: Insights from early aftershock sequences driven by afterslip following three 2021–2022 moderate-large events

International Journal of Applied Earth Observations and Geoinformation
Early aftershock sequences and afterslip provide key insights into crust rheology and the triggering mechanisms of seismicity sequences. Three recent moderate-large strike-slip earthquakes in eastern Tibet, including the 2021 Yangbi Mw 6.1, the 2021 ...

The 2025 Mw 8.8 Kamchatka Megathrust: A Rapid Recurrence With Complex Heterogeneous Rupture

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract On 29 July 2025, a Mw 8.8 earthquake struck Kamchatka, ∼50 km from the 1952 Mw 9.0 megathrust hypocenter, exhibiting a comparable aftershock zone. We resolve the kinematic rupture process and slip distribution by combining teleseismic waveforms with high‐quality tsunami data.

Temporarily Increased Recurrence Rate of Shallow Slow Slip Events Driven by Significant Afterslip Following the 2012 Mw 7.6 Nicoya Earthquake

Geophysical Research Letters
Slow slip events (SSEs) release tectonic strain without causing sudden ground shaking. SSEs have been observed at many subduction zones, some dynamically triggered by stress changes due to the passage of seismic waves.

Footprints of past earthquakes revealed in the afterslip of the 2010 Mw 7.8 Mentawai tsunami earthquake

, 2016
The 2010 Mw 7.8 Mentawai tsunami earthquake marks one of the first tsunami earthquakes to have postseismic deformation observed by geodetic instruments. The Sumatran GPS Array has recorded the postseismic deformation following this event continuously for
