Tectonic Stress as the Driving Mechanism for Dike Opening in an Oblique Rift Setting: A Deformation Model of the 2021 Fagradalsfjall Dike, Iceland

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Repeated dike‐intrusions often occur in zones where extensional stress has accumulated. Still, geodetic modeling of observed dike‐induced ground deformation often ignores the contribution of tectonic stress. On the obliquely spreading Reykjanes Peninsula, Iceland, tectonic strain build‐up had been geodetically documented for three decades when

Water Reservoirs in the Lower Mantle Beneath Northeastern Asia

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Water in the mantle controls mantle convection and chemical transport processes within Earth's interior. However, whether the water in the lower mantle is primordial or recycled remains an open question. Here we report an electrical structure consisting of two stepped high‐conductivity anomalies crossing the 660‐km interface beneath ...

Long‐Lasting Volcanism of the Moon Aided by the Switch in Dominant Mechanisms of Magma Ascent: Role of Localized Radioactive Enrichment in a Numerical Model of Magmatism and Mantle Convection

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Significant volcanic activity continued for billions of years since 3.5–4 Gyr ago in the Procellarum KREEP Terrane (PKT) of the Moon, but not so significant outside the PKT. To understand this volcanic history, we developed a 2‐D numerical model of magmatism and mantle convection; the effects of the PKT on lunar evolution are considered by ...
