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 ...

Repeating microearthquake sequences interact predominantly through postseismic slip [PDF]
Nature Communications, 2016 Studying small repeating earthquakes enables better understanding of fault physics and characterization of fault friction properties. Some of the nearby repeating sequences appear to interact, such as the 'San Francisco' and 'Los Angeles' repeaters on the creeping section of the San Andreas Fault.

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.

Postseismic deformation and the strength of ductile shear zones [PDF]
Earth, Planets and Space, 2014 A good understanding of the rheology and strength of the whole crust is needed to obtain a physics-based earthquake prediction models. However, geodynamics-based and laboratory-based strength estimates disagree. Geodynamics tend to indicate that the actual strength of the plastic crust is less than deduced from laboratory experiments.

A Bayesian Framework for Empirical Estimation of Post‐Earthquake Building Inspection Time
Earthquake Spectra, Volume 42, Issue 3, August 2026.Building safety inspections can be an impeding determinant of post‐earthquake recovery, yet their durations remain inadequately quantified because fine‐grained operational data are rarely available. Here, we present a probabilistic Bayesian framework to quantify building‐level inspection time, calibrated against a comprehensive multiagency dataset from

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Understanding the spatio‐temporal variations in the physical properties of the Earth's crust is crucial for comprehending the dynamic processes linked to earthquakes. Conventional seismometer‐based analyses have limitations in spatio‐temporal resolution due to the sparse station distribution.

Coseismic and postseismic motion of a landslide: Observations, modeling, and analogy with tectonic faults [PDF]
Geophysical Research Letters, 2014 AbstractWe document the first time series of a landslide reactivation by an earthquake using continuous GPS measurements over the Maca landslide (Peru). Our survey shows a coseismic response of the landslide of about 2 cm, followed by a relaxation period of 5 weeks during which postseismic slip is 3 times greater than the coseismic displacement itself.

Postseismic Deformation in the Northern Antarctic Peninsula Following the 2003 and 2013 Scotia Sea Earthquakes [PDF]
, 2023 Large earthquakes in the vicinity of Antarctica have the potential to cause postseismic viscoelastic deformation affecting measurements of displacement that are used to constrain models of glacial isostatic adjustment (GIA).

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.
