DOI: 10.1073/pnas.2406386121
Abstract: Significance Recent advancements in seismology have unveiled that ULVZs are not confined solely to low-velocity zones at the CMB but also discernible within high-velocity regions, which is not well understood. Delivery of water to the… read more here.

DOI: 10.1093/gji/ggz345
Abstract: Low-velocity layers within the crust can indicate the presence of melt and lithologic differences with implications for crustal composition and formation. Seismic wave conversions and reverberations across the base of the crust or intracrustal discontinuities,… read more here.
