Slab Dehydration Observed Down to Lower Seismicity Plane Depths in the Northern Chile Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We present a high‐resolution local earthquake tomography model that constrains the distribution of hydration and dehydration processes within the subducting Nazca slab beneath Northern Chile. We image a distinct downdip transition from high Vp/Vs (∼1.75) over low Vp/Vs (∼1.65) to a homogeneously high Vp/Vs slab at depths of ≥ ${\ge} $85 km ...

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.

Seismic Attenuation Reveals Fault and Forearc Structure Across the Subduction‐Collision Transition in Southern Taiwan

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The Southern Array for the Lithosphere and Uplift of Taiwan Experiment (SALUTE) provides a new window into the subduction‐collision transition zone in southern Taiwan, where the Eurasian Plate‐Luzon Arc convergence drives intense orogeny and crustal deformation. Using dense P‐ and S‐wave spectral amplitude data recorded by SALUTE and a quality

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...
