Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Abstract Chlorite is thought to be one of the major water‐carrying phases in subduction zones, both within the slab and in the mantle wedge. Its presence has previously been linked to common seismological observations at subduction zones, including P and S wave anisotropy as well as high VP/VS ratios (>1.8) in the mantle wedge.

Imaging the Alpine Collision With Seismic Radial Anisotropy
Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...

Abstract Reconciling Earth's thermal evolution with geochemical observations remains a fundamental challenge, as parameterized convection models typically predict high present‐day Urey ratios inconsistent with geochemical estimates. Previous studies propose that if mantle water concentration varies inversely to mantle temperature, it would weaken the ...

Inception and Plate Evolution of the Lau Back‐Arc Basin From Plate Boundary Refinements
Abstract Back‐arc basins are important settings for crustal growth that form in response to both near and far‐field tectonic influences. To better understand the processes that control back‐arc basin initiation and evolution, we present a refined model of the kinematics of opening of the Lau Basin, embedded in a global plate model.
