Impact of Mantle Velocity Uncertainty on Receiver‐Function Imaging of the Transition Zone
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Seismological estimates of the 400‐km and 670‐km mantle discontinuities (d400 and d670) are crucial for understanding the thermochemical structure and dynamics of the mantle transition zone (MTZ). However, artifacts from using ray theory and uncertainties in mantle velocity structure can affect topographic mapping of these boundaries.

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 ...

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.
