Seismic observations suggest that the Earth's inner core has a complex structure (e.g., the isotropic layer at the top, innermost inner core, and hemispherical dichotomy). These characteristics are believed to reflect the history of dynamics and temperature profile of the inner core. One ...
Properties of the Earth's inner – outer core transition by characteristics of seismic waves of PKIIKP and PKPc-diff Geophysical Research AbstractsKrasnoshchekov, DmitryOvtchinnikov, VladimirUsoltseva, Olga
Learn about the inner core of the Earth. Discover the inner core composition and characteristics, the inner core elements, and numerous inner core facts. Related to this Question Why is the Earth's outer core important? Why is the Earth's inner core hot?
On the basis of the characteristics of the inner core, the equivalent inner core ellipsoid is introduced. The inertia moments of the equivalent inner core ellipsoid are calculated, and then the largest contribution of the inner core to the difference between the Earth's principal inertia moments ...
(S- waves). Primary and secondary waves pass deep within Earth and therefore are the mostinstructive. Study of abrupt changes in the characteristics of seismic waves at different depths provides the basis for a threefold division of Earth into a central core; a thick, overlying mantle: and a...

Static tilt between the inner core and mantle To further obtain the orientation of the static tilt angleθand its magnitude, we need to determine the fluctuation characteristics of the axial torqueГz(∝dΔLOD/dt; see Methods) exerted on the mantle. Hence, we directly fit the ~8.5 yr si...
An inner part of the inner core with a distinct form of anisotropy has been suggested, but there is considerable uncertainty regarding its existence and characteristics. Here we analyse the autocorrelation of earthquake coda measured by global broadband seismic arrays between 1992 and 2012, and find...

The seismological properties of Earth’s inner core are key to understanding its composition, dynamics and growth history. Within the inner core, fine-scale heterogeneity has previously been identified from backscattering of high-frequency compressional waves. Here we use historical earthquake and explosio...
