Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Competing Effects of Elastic Heterogeneity and Viscous Flow on Interseismic Coupling at Cascadia

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Interseismic coupling maps are important tools for estimating future earthquake hazard at subduction zones. Often interseismic coupling is estimated from surface velocities using a homogeneous elastic Earth model. However, inversions that incorporate viscoelastic mantle flow or elastic heterogeneity show that each can change the spatial ...

Large fault slip peaking at trench in the 2011 Tohoku-oki earthquake

Nature Communications, 2017
The 2011 Tohoku-oki earthquake slip occurred on the shallowest part of the megathrust, but the nature of the shallow slip has been poorly constrained. Here, the authors model bathymetry differences before and after the earthquake to determine that the ...

Potential Bias in Inferred Megathrust Slip Rates Induced by the Neglect of Material Heterogeneity

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Accurate knowledge of the pattern of interseismic coupling on megathrusts is critical to preparing for future earthquakes and tsunamis. However, published models for a given fault zone commonly differ widely, making hazard assessment difficult.

Stress, rigidity and sediment strength control megathrust earthquake and tsunami dynamics

, 2020
Megathrust faults host the largest earthquakes on Earth which can trigger cascading hazards such as devastating tsunamis. Determining characteristics that control subduction zone earthquake and tsunami dynamics is critical to mitigate megathrust hazards,

Chilean megathrust earthquake recurrence linked to frictional contrast at depth [PDF]

, 2018
Fundamental processes of the seismic cycle in subduction zones, including those controlling the recurrence and size of great earthquakes, are still poorly understood.

Probabilistic Hazard Assessment of Coseismic Elastic Surface Deformation for the Leech River Valley–Devil's Mountain Fault System Using Stochastic Source Modeling

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...
