Seismo‐ and Tsunami‐Traveling Ionospheric Disturbances of the 29 July 2025 M8.8 Kamchatka Earthquake Observed by CW‐HF Doppler Sounding Systems and Ionosondes in Taiwan and Japan

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.

HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with in situ satellite measurements, enabling a comprehensive study of ...

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.

Post‐Sunset Merging of Equatorial Ionization Anomaly Crests Into a Single Peak Over ∼35° Longitude During the 19 January 2026 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We investigate the nighttime equatorial ionosphere during the 19 January 2026 geomagnetic storm using Global‐scale Observations of the Limb and Disk OI 135.6 nm observations and ground‐based GPS Total Electron Content. The observations reveal a pronounced longitudinal asymmetry in the post‐sunset equatorial ionization anomaly (EIA).
