Global GNSS Observation of Mesoscale Ionospheric Irregularities (2006–2024)
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Mesoscale ionospheric irregularities are statistically investigated using an unprecedented 19‐year long‐term global GNSS (Global Navigation Satellite System) TEC (total electron content) data set. These irregularities are represented by ionospheric fluctuations within a 5°× ${}^{\circ}\times $ 3.75° ${}^{\circ}$ (latitude by longitude) region ...

Bayesian Approach to Ionospheric Elementary Current Systems Using Differentiable Basis Functions
Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.Abstract Spherical elementary current systems (SECS) have become a widely used tool to model vector fields on spherical surfaces in ionospheric data analysis. The systems were originally formulated using point sources for the divergence and curl of the fields. In this paper we present a flexible alternative formulation, showing how continuous functions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract The southeastern Tibetan Plateau (SETP) plays a pivotal role in accommodating intra‐continental deformation driven by the ongoing India‐Eurasia convergence. However, its contemporary surface vertical motions and the underlying geodynamic processes remain highly debated.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract La Soufrière de Guadeloupe volcano exhibits microseismic activity dominated by volcano‐tectonic repeaters, mainly occurring in swarms clustered in a sub‐vertical conduit beneath the Tarissan acid lake (TAS) at depths less than 800 m. Following the April 2018 earthquake (Mlv 4.1), which likely damaged the dome, swarms intensified and show ...

Effects of Hydrogen on Fe‐S Alloys and Their Implications for the Martian Core
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Meteorites suggest the Martian core comprises iron (Fe) or iron‐nickel (Fe‐Ni) alloy with sulfur (S) identified as the primary light element. The InSight data revealed a larger, less dense Martian core than previously estimated, indicating additional light elements.
