Theoretical Modeling Rayleigh-Love Coupling and Its Implications
AGU 2024
seismology | 12 december 2024
Xiongwei Liu, Michael H. Ritzwoller
Surface wave anisotropy and the coupling between Rayleigh and Love waves have been modeled primarily using first-order non-degenerate perturbation the...

Depth-Dependent Seismic Azimuthal Anisotropy Beneath the Juan de Fuca-Gorda Plates and the Aleutian Subduction Zone
AGU 2024
seismology | 11 december 2024
Chuanming Liu, Thorsten W. Becker, Anne Sheehan, M...
Seismic anisotropy is one of the most critical observables for decoding the tectonic history and ongoing dynamics of oceanic plates. Benefiting from r...
