Equilibrium Silicon Isotope Fractionation in Eclogites and Granites Constrained by Single Crystal X‐Ray Diffraction and the Force Constants Approach

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Using our recently developed X‐ray diffraction based force constants approach, we have determined the equilibrium Si isotope fractionation between omphacite/garnet, quartz/kyanite, and quartz/zircon at temperatures relevant to the petrogenesis. We find that Na strongly affects the Si isotope fractionation between omphacite and garnet.

Slow Rupture, Long Rise Times, and Multi‐Fault Geometry: The 2020 M6.4 Southwestern Puerto Rico Mainshock

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The M6.4 mainshock of the southwestern Puerto Rico seismic sequence on 7 January 2020, was one of the most impactful modern earthquakes in the northeastern Caribbean. Due to its offshore location and complex aftershock distribution, its source kinematics remain poorly constrained.

Ionospheric Disturbances in GNSS TEC Data: SpaceX Falcon 9 Deorbit Maneuvers Over CONUS in April–May 2024

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Traveling ionospheric disturbances (TIDs) driven by a large number of internal and external sources are detectable with dense networks of ground‐based Global Navigation Satellite System (GNSS) receivers' measurements of total electron content (TEC).

Detection of Landslide‐Generated Tsunami by Shipborne GNSS Precise Point Positioning

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Precise point positioning (PPP) of ships using Global Navigation Satellite System (GNSS) data reveals the precise movements of marine vessels. This method may quantify anomalies in sea surface height with implications for oceanographic monitoring, exploration, and tsunami warning. The GNSS PPP data from the R/V Sikuliaq, a research ship of the

Large Megathrust Earthquakes Tend to Sustain an Increasingly Longer Duration Than Expected

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract The moment‐duration (M0‐T) scaling law reveals fundamental earthquake physics across various sizes and tectonic settings. However, the validity of the cubic relation (M0 ∝ T3) inferred for large (Mw ≥ 7) megathrust events has been recently questioned due to the scarcity of observations and similarities to slow earthquakes.
