Shear softening of earth's inner core as indicated by its high poisson ratio and elastic anisotropy [PDF]

Fundamental Research
Earth's inner core exhibits an unusually high Poisson ratio and noticeable elastic anisotropy. The mechanisms responsible for these features are crucial to understanding the nature of Earth's core.

The anisotropy of hexagonal close-packed iron under inner core conditions: the effect of light elements

Earth and Planetary Physics, 2022
In recent decades, global seismic observations have identified increasingly complex anisotropy of the Earth’s inner core. Numerous seismic studies have confirmed hemispherical variations in the inner core’s anisotropy.

Comment on “Inner Core Rotation Captured by Earthquake Doublets and Twin Stations” by Yang and Song

Geophysical Research Letters, 2023
Yang & Song (2022, https://doi.org/10.1029/2022GL098393) first claimed existence of Earth's inner core differential rotation based on the waveform similarity of two neighboring stations AAK and KZA across an earthquake doublet and then postulated a local

Inner Core Rotation Captured by Earthquake Doublets and Twin Stations

Geophysical Research Letters, 2022
The Earth's solid inner core (IC) is generally believed to rotate relative to the mantle, but the proposal remains controversial. Here we use seven waveform doublets in the South Sandwich Islands region with time lapses of 5.8–17.0 years that are ...

Repeating earthquakes and temporal changes of the Earth's inner core

地球与行星物理论评, 2021
One of the most intriguing features of the Earth's inner core is its temporal variability over decadal time scale. Time-varying sesismic waves traversing the inner core, from high-quality repeating earthquakes, provide unequivocal evidence for the ...

A Simple Method for Predicting Intensity Change Using the Peak Time Lag Between Lightning and Wind in Tropical Cyclones

Geophysical Research Letters, 2021
Using lightning data from the World‐Wide Lightning Location Network (WWLLN) and tracking data for Tropical Cyclones (TCs) from the China Meteorological Administration (CMA), the relationship between the peak time lag (Tlag) and the wind intensity change ...

The Gravity Signal of Mercury's Inner Core

Earth and Space Science, 2022
In a reference frame rotating with Mercury's mantle and crust, the inner core and fluid core precess in a retrograde sense with a period of 58.646 days.
