Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...

AGU AdvancesSlow slip events (SSEs) have been observed in spatial and temporal proximity to megathrust earthquakes in various subduction zones, including the 2014 Mw 7.3 Guerrero, Mexico earthquake which was preceded by a Mw 7.6 SSE.

Fast, accurate solutions for curvilinear earthquake faults and anelastic strain [PDF]
, 2018 Imaging the anelastic deformation within the crust and lithosphere using surface geophysical data remains a significant challenge in part due to the wide range of physical processes operating at different depths and to various levels of localization that

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Impact of a tsunami generated at the Lesser Antilles subduction zone on the Northern Atlantic Ocean coastlines [PDF]
Advances in Geosciences, 2014 On 11 March 2011, a Mw ~ 9.0 megathrust earthquake occurred off the coast of Tohoku, triggering a catastrophic tsunami reaching heights of 10 m and more in some places and resulting in lots of casualties and destructions.
