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.

Late Holocene great earthquakes in the eastern part of the Aleutian megathrust [PDF]

Quaternary Science Reviews, 2014
Abstract The great earthquake, Mw 9.2, of AD 1964 may not be typical of other megathrust earthquakes in the region during the last 4000 years. We present new field data from three sites: Copper River Delta, the lower Katalla River valley and Puffy Slough, to enhance the temporal and spatial resolutions of the paleoseismic records of multiple great ...

Triggered crustal earthquake swarm across subduction segment boundary after the 2016 Pedernales, Ecuador megathrust earthquake

, 2020
Megathrust ruptures and the ensuing postseismic deformation cause stress changes that may induce seismicity on upper plate crustal faults far from the coseismic rupture area.

Characteristics of viscoelastic crustal deformation following a megathrust earthquake: discrepancy between the apparent and intrinsic relaxation time constants [PDF]

, 2017
The viscoelastic deformation of an elastic–viscoelastic composite system is significantly different from that of a simple viscoelastic medium. Here, we show that complicated transient deformation due to viscoelastic stress relaxation after a megathrust ...

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.

Stress Field and Megathrust Strength in the Western Hellenic Subduction System: Insights From the 2024 Mw 5.9 Strofades Earthquake Sequence, Greece

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A M5.9 earthquake occurred on 29 March 2024, offshore near the Strofades Islands, in the western Hellenic Subduction System. Here we present high‐precision earthquake locations and focal mechanisms that suggest the rupture of a NNE‐SSW striking, left‐lateral strike‐slip fault.

Historical and recent large megathrust earthquakes in Chile

Tectonophysics, 2018
Abstract Recent earthquakes in Chile, 2014, Mw 8.2 Iquique, 2015, Mw 8.3 Illapel and 2016, Mw 7.6 Chiloe have put in evidence some problems with the straightforward application of ideas about seismic gaps, earthquake periodicity and the general forecast of large megathrust earthquakes.

Cluster Analysis of Long-Period Ground-Motion Simulation Data with Application to Nankai Trough Megathrust Earthquake Scenarios

, 2018
We developed a clustering method combining principal component analysis and the k-means algorithm, which classifies earthquake scenarios based on the similarity of the spatial distribution of earthquake ground-motion simulation data generated for many ...

Evaluation of Earthquake‐Induced Slope Displacements in Greater Vancouver Based on Probabilistic Framework and Using NBCC 2020 and EqDisp Code Platform

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Engineers frequently use simplified seismic slope displacement procedures to evaluate the performance of earth structures and natural slopes. Current practices typically adopt Newmark‐type and semi‐empirical seismic displacement prediction models (SDPMs) to estimate the seismic slope displacements (D) based on ground motion intensity measures at a ...
