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 …

Earth's inner core acquires texture as it solidifies within the fluid outer core. The size, shape
and orientation of the mostly iron grains making up the texture record the growth of the inner …

Full‐waveform inversion (FWI) optimizes the subsurface properties of geophysical Earth
models in such a way that the modeled data, based on these subsurface properties, match …

Temporal changes of inner-core (IC) seismic phases have been confirmed with high-quality
waveform doublets. However, the nature of the temporal changes is still controversial. We …

The inner core has been inferred to change its rotation rate or shape over years to decades
since the discovery of temporal variability in seismic waves from repeating earthquakes that …

The nature of the inner core (IC) temporal changes is of great importance in understanding
the deep earth dynamics. The comment by Tian and Wen (2023, https://doi. org/10.1029 …

Differential travel times and waveforms of PKIKP and PKiKP phases in the 129°–141°
distance range, deconvolved for the effects of source time functions and average mantle …

The rate that Earth's inner core rotates relative to the mantle and crust has been debated for
decades. Nonrotational processes, including internal deformation and flow in the outer core …

Increasing complexity of Earth's inner core has been revealed in recent decades as the
global distribution of seismic stations has improved. The uneven distribution of earthquakes …

We stack amplitudes of over 10 000 high-frequency (∼ 1 Hz) PKP precursor waveforms,
amassed from broad-band global seismic data with source–receiver distances between …
