Tsunami Traveling Ionospheric Disturbances Triggered by the 29 July 2025 Mw 8.8 Kamchatka Earthquake Observed in Japan and Taiwan

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated notable seismic and tsunami waves. The total electron content (TEC) derived by more than 1,400 ground‐based global navigation satellite system (GNSS) receiving stations in Japan and Taiwan is employed to examine the spatiotemporal evolution of seismic‐ and tsunami‐traveling ionospheric ...

Controlling of the F Region Plasma Structures by the E Region Conductance in the Auroral Ionosphere

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract At high latitudes, the E and F regions of the ionosphere are strongly coupled through nearly vertical magnetic field lines. To simultaneously and directly relate the E and F regions' plasma structures, we ran a coordinated conjunction campaign between Swarm satellites and Incoherent Scatter Radar in Tromsø, Norway, during a moderate ...

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

SWOT High‐Rate Raster Data Reveals Antarctic Ice Shelf Motion and Change in Response to Ocean and Ice Dynamics

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The NASA/CNES Surface Water and Ocean Topography (SWOT) swath‐mapping radar altimetry satellite mission, launched in December 2022, provides repeat‐track coverage to about ±78.2° latitude every 21 days, sampling many of Antarctica's most dynamic ice shelves that play key roles in constraining mass loss from the grounded ice sheet ...

Double Trouble: Two Active Magma Reservoirs Identified at Masaya Volcano, Nicaragua, Using Satellite Geodesy

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We analyze and model ground deformation at Masaya volcano, Nicaragua, using Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series spanning January 2018–February 2024. Time series show the Masaya Central Reservoir (MCR) experienced ∼3 cm of line of sight (LOS) displacement away from the satellite north of the Santiago crater ...
