OH Airglow for Ionospheric Seismology Applications—From Instrumental Noise Characterization to Rayleigh Waves Detection Threshold

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Airglow layers are powerful tracers of upper‐atmosphere dynamics because of their sensitivity to a broad spectrum of atmospheric wave phenomena. Seismic activity, and in particular Rayleigh waves, constitutes a forcing mechanism capable of generating infrasonic waves in the atmosphere.

Normal Modes in a Coupled Earth Model: A New Perspective on the Compliance Method

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract To understand the compliance parameters observed for atmospheric pressure waves, we develop a normal‐mode approach for a coupled Earth model that includes the atmosphere and the solid Earth. Extending the method of Press and Harkrider to a coupled Earth model, we introduce two new features.

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano reached the mesosphere

, 2022
Explosive volcanic eruptions can loft ash, gases, and water into the stratosphere, which affects both human activities and the climate. Using geostationary satellite images of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, we find

Forced and free waves of simulated volcanic meteo-tsunamis in the South China Sea

npj Natural Hazards
Volcanic meteo-tsunamis (VMTs) are rare, devastating phenomena first recognised after the 1883 Krakatau eruption in Indonesia and recently quantified following the 2022 Hunga Tonga-Hunga Ha’apai volcanic eruption in the Kingdom of Tonga.

Monitoring volcanic activity with distributed acoustic sensing using the Tongan seafloor telecommunications cable

Earth, Planets and Space
The devastation caused by the January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano (HTHH) in the Tongan archipelago reminded us of the importance of monitoring shallow-sea volcanic activity.
