Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Doppler frequency shifts (DFSs) recorded by continuous wave‐high frequency Doppler sounding systems and ionograms observed by five ionosondes in Taiwan and Japan are used to study three‐dimensionally seismo‐ and tsunami‐traveling ionospheric disturbances (STIDs and TTIDs) triggered by the 29 July 2025 Mw8.8 Kamchatka earthquake.

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Global Evidence for Off‐Axis Flexural Modification of Abyssal Hill Faults at Mid‐Ocean Ridges
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract Young oceanic lithosphere flexes as axial topography decays across mid‐ocean ridge shoulders, yet this deformation has been quantified at only a few segments, leaving its global expression poorly constrained. We analyzed 50 across‐axis bathymetric profiles from 21 regions spanning slow to fast spreading rates, identified 1,201 abyssal‐hill ...

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Volcano‐tectonic (VT) earthquakes generated during dike propagation provide useful constraints on stress changes in volcanic systems. During the 1998 pre‐eruptive unrest at Piton de la Fournaise, ∼600 VT earthquakes were recorded. Using manually picked first‐motion polarities and corrected station metadata, we calculated more than 400 high ...

Gravitational Stability of Hydrated SiO2 and Basaltic Crust in the Lower Mantle
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract We determined thermal equations of state of hydrated stishovite and CaCl2‐type SiO2 up to 100 GPa and 3,000 K to assess the gravitational stability of hydrated stishovite and basaltic crust in the lower mantle. Using machine‐learning based atomistic simulations, we examined three hydrogen dissolution mechanisms: hydrogarnet‐type, interstitial ...
