The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

Impact Craters Reveal a Deeper Rock‐Poor Regolith in the Lunar Highlands

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The only measurements of the highlands regolith occurred at the Apollo 14 and 16 landing sites, finding 10–15 m thick regolith; however, we show that the Apollo landing sites are anomalous due to their proximity to rare, highlands rocky craters and because they landed atop basin ejecta. Through observations of rocky crater populations, we show
