Seismic tomography has been a vital tool in probing the Earth's internal structure and
enhancing our knowledge of dynamical processes in the Earth's crust and mantle. While …

▪ Abstract We review the present status of global mantle tomography and discuss two main
classes of models that have been developed in the past 10 years: P velocity models based …

Anomalous boundary layer structure at the core‐mantle boundary (CMB) is investigated
using a global set of broadband SKS and SPdKS waves from permanent and portable …

Since the discovery of the inner core in 1936, no additional spherical subshell of the Earth
has been observed. Based on an extensive seismic data set, we propose the existence of an …

Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …

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 …

Seismology has come a long way in providing insights into Earth's internal structure and
dynamics. Among many forward and inverse geophysical techniques developed, full …

The days when the Earth's inner core (IC) was viewed as a homogeneous solid sphere
surrounded by the liquid outer core (OC) are now behind us. Due to a limited number of data …

We investigate the hemispherical pattern in inner core velocity anisotropy using a new and
independent high‐quality data set of PKPbc‐PKPdf and PKPab‐PKPdf body wave …

Seismic traveltime anomalies of waves that traverse the uppermost 100–200 km of the outer
core have been interpreted as evidence of reduced seismic velocities (relative to radial …
