Seismic tomography reveals 2 extensive regions in the lowermost mantle, beneath Africa
and the Pacific, that exhibit lower-than-average seismic wave speeds. These regions have …

Recent seismological work has revealed new structures in the boundary layer between the
Earth's core and mantle that are altering and expanding perspectives of the role this region …

The fourth edition of Physics of the Earth maintains the original philosophy of this classic
graduate textbook on fundamental solid earth geophysics, while being completely revised …

A new model of whole mantle P-wave tomography is determined with a novel approach. A
grid parameterization instead of blocks and spherical harmonics is adopted to express the …

Seismic recordings made during the InSight mission suggested that Mars's liquid core would
need to be approximately 27% lighter than pure liquid iron,, implying a considerable …

A new global tomography approach has been used to study the deep structure and
dynamics of hotspots and mantle plumes. In this approach, depth variations of the Moho …

We have compiled all previous ultralow velocity zone (ULVZ) studies, and digitized their
core‐mantle boundary (CMB) sampling locations. For studies that presented sampling …

Seismological observations reveal patches of low-velocity anomalies at the core–mantle
boundary known as ultralow-velocity zones. Despite recent advances, their origin and …

Understanding the process underlying the origin of Earth magnetic field is one of the
greatest challenges left to classical Physics. Geomagnetism, being the oldest Earth science …

Linear chains of volcanic ocean islands are one of the most distinctive features on our
planet. The longest, the Hawaiian–Emperor Chain, has been active for more than 80 million …
