The lowermost mantle right above the core-mantle boundary is highly heterogeneous
containing multiple poorly understood seismic features. The smallest but most extreme …

Ultralow velocity zones (ULVZs) and seismic anisotropy are both commonly detected in the
lowermost mantle at the edges of the two antipodal large low velocity provinces (LLVPs) …

The core-mantle boundary (CMB) is a complex and poorly understood region of the Earth.
The existence of melt or partial melt at the CMB is strongly debated with evidence coming …

Strong waveform complexities, including multipathing of the S diffracted phase and rapid
changes in differential ScS‐S times, are observed for multiple deep Fiji earthquakes …

It is well known that regions of the lowermost mantle—D ″—exhibit significant seismic
anisotropy. Identifying a unique mechanism for seismic anisotropy in D ″and interpreting …

Parameterised by the Love number k2 and the tidal quality factor Q, and inferred from lunar
laser ranging (LLR), tidal dissipation in the Moon follows an unexpected frequency …

Geodynamic modeling and seismic studies have highlighted the possibility that a thin layer
of low seismic velocities, potentially molten, may sit atop the core‐mantle boundary but has …

Two‐phase flow, a system where Stokes flow and Darcy flow are coupled, is of great
importance in the Earth's interior, such as in subduction zones, mid‐ocean ridges, and …

Seismic energy arriving before the compressional (P) wave passing through the core (PKP),
called PKP precursors, have been detected for decades, but the origin of those arrivals is …

Recent seismological studies challenge the traditional view that the interface between the
core and mantle is a straightforward discontinuity. As seismology is pushed to its …
