Scattering evidence for an ancient subducted slab using the novel raypath P*PKP
AGU 2024
study of earth's deep interior | 13 december 2024
Hao Zhang, John E. Vidale, Wei Wang
We observe high-frequency scatterers consistent with the interpretation of a tabular high velocity structure under the Indian Ocean as an ancient subd...

Aftershocks on the planar rupture surface of the deep-focus MW 7.9 Bonin Islands earthquake
AGU 2024
volcanology, geochemistry and petrology | 11 december 2024
Hao Zhang, John E. Vidale, Wei Wang
The largest deep-focus earthquakes tend to occur in isolated settings, and so their aftershock sequences are invaluable for comprehending the interact...

No temporal change seen in high-frequency waves scattered near the CMB
AGU 2024
study of earth's deep interior | 10 december 2024
Ruoyan Wang, John E. Vidale, Wei Wang
The core-mantle boundary (CMB) and the outermost core are dynamic and heterogeneous regions in which time-dependent flow could generate observable cha...

Localized Core-derived Sediments at the Top of Earth’s Outer Core
AGU 2024
study of earth's deep interior | 09 december 2024
Tianyu Cui, Wei Wang, Wenzhong Wang, John E. Vidal...
Earths core-mantle boundary (CMB) is the most dramatic discontinuity within Earth's interior. It separates the solid silicate mantle from the molten m...

Earth’s inner core may both rotate and deform within years
AGU 2024
study of earth's deep interior | 09 december 2024
John E. Vidale, Wei Wang, Ruoyan Wang, Guanning Pa...
The solid inner core (IC), anchored amidst the liquid outer core, has been inferred to rotate or change over years to decades since the 1996 discovery...

Waveform Changes in Reflection and Transmission due to Varying Scatterers for Inner Core Scenarios
AGU 2024
study of earth's deep interior | 09 december 2024
Ruoyan Wang, John E. Vidale
Fine-scale heterogeneity in Earth's inner core (IC) has been identified from scattering of PKIKP. The differential rotation of the IC is expected to a...

No Temporal Change Seen in High‐Frequency Waves Scattered Near the Core‐Mantle Boundary
GEOPHYSICAL RESEARCH LETTERS
04 december 2024
Ruoyan Wang, John E. Vidale, Wei Wang
The core‐mantle boundary (CMB) and the outermost core are dynamic and heterogeneous regions with time‐dependent flows. We examine two s...
