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 ...

Andean tectonics: Implications for Satellite Geodesy [PDF]
Current knowledge and theories of large scale Andean tectonics as they relate to site planning for the NASA Crustal Dynamics Program's proposed high precision geodetic measurements of relative motions between the Nazca and South American plates are ...

Regional‐to‐Global Tectonic and Trench‐Morphology Effects of Oceanic Plateau Subduction
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Regional geodynamic modeling has shown that oceanic plateau subduction can modify the slab behavior. However, few studies have explored these interactions beyond 100 Myr in 3‐D spherical models. Using 3‐D spherical mantle convection models with self‐consistent plate‐like behavior, we investigate how the geometry and rheological properties of ...

Dynamic interpretation of geoid anomalies [PDF]
The NASA Geodynamics program has as two of its missions precise determination of spatial variations in earth's geopotential (or geoid) and highly accurate monitoring of polar motion, including changes in the length of day (LOD).
