Dynamic history of the inner core constrained by seismic anisotropy

DA Frost, M Lasbleis, B Chandler, B Romanowicz - Nature Geoscience, 2021 - nature.com
Progressive crystallization of Earth's inner core drives convection in the outer core and
magnetic field generation. Determining the rate and pattern of inner-core growth is thus …

Seismic tomography of the uppermost inner core

S Burdick, L Waszek, V Lekić - Earth and Planetary Science Letters, 2019 - Elsevier
Seismic body wave and normal mode analyses have revealed that the inner core is solid,
strongly anisotropic, and characterized by dramatic quasi-hemispherical differences in …

Double-diffusive translation of Earth's inner core

R Deguen, T Alboussière… - Geophysical Journal …, 2018 - academic.oup.com
The hemispherical asymmetry of the inner core has been interpreted as resulting from a high-
viscosity mode of inner core convection, consisting in a translation of the inner core. A …

Sharpness of the hemispherical boundary in the inner core beneath the northern Pacific

R Iritani, H Kawakatsu, N Takeuchi - Earth and Planetary Science Letters, 2019 - Elsevier
The hemispherical nature of heterogeneities of the isotropic velocity and attenuation of the
inner core has been extensively studied by seismic observations, but consensus on the …

An attenuating, isotropic and heterogeneous uppermost inner core: evidence from global PKiKP-PKIKP amplitude ratio tomography

M Ivan, L Petrescu, R Wang - Geophysical Journal International, 2022 - academic.oup.com
The Earth's inner core is solidifying from the liquid outer core, where convection currents
power the geodynamo. Constraining properties of the inner core is fundamentally important …
