Viscoelastic Relaxation Following the 2001 Mw 8.4 Arequipa Earthquake and Its Impact on the Interseismic Coupling of the South Peru Megathrust

Geophysical Research Letters
Postseismic displacements associated with the 2001 Mw 8.4 Arequipa earthquake have been observed on a continuous GNSS timeseries in Arequipa for over two decades (∼30 cm on horizontal components).

Inner forearc faults in northern Cascadia do not accommodate elastic strain driven by the megathrust seismic cycle

Seismica
We employ numerical models to explore the connection between subduction zone coupling or megathrust rupture and upper plate faults in the northern Cascadia forearc.

High Resolution Focal Mechanisms and Stress Field Orientation in Southern Italy From Short‐Term Dense Arrays

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Understanding fault geometry and mechanics is key to interpreting the seismotectonic setting of a region. We analyze data from a 1‐year dense seismic array deployment in Southern Italy to infer focal mechanisms and stress field from low‐magnitude earthquakes using machine‐learning techniques.

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

Interseismic megathrust coupling beneath the Nicoya Peninsula, Costa Rica, from the joint inversion of InSAR and GPS data [PDF]

, 2015
The Nicoya Peninsula, Costa Rica, was struck by a long-anticipated and gap-filling Mw 7.6 earthquake in 2012. To study interseismic strain accumulation on the megathrust beneath the Nicoya Peninsula, we present an improved interseismic coupling model by ...

Subducted Seamounts Promote Slow and Fast Slip Throughout the Seismic Cycle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract The role of subducted seamounts on slip behavior is debated: they have been proposed to act as seismic asperities, or to favor aseismic slip and rupture arrest. We use numerical simulations and fracture mechanics to investigate how seamounts affect the seismic cycle.

Bayesian Calibration of Dynamic Models of Earthquake Sequences Using Observations From Past Large Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Physics‐based models of the earthquake cycle could be used for time‐dependent hazard assessment. For such an application, their parameters must be calibrated so that simulated earthquake sequences reproduce the statistics of past earthquakes, including recurrence statistics and magnitudes. This is challenging because the dynamics are described

Upper plate tectonic stress state may influence interseismic coupling on subduction megathrusts

, 2012
We document a correlation between along-strike variation in interseismic coupling depth on subduction interfaces, and the upper plate tectonic stress state in New Zealand, Vanuatu, and southwest Japan.

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

Geophysical Research Letters
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 ...
