Probing signals of atmospheric gravity waves excited by the July 29, 2021 MW8.2 Alaska earthquake

Geodesy and Geodynamics
It is commonly believed that the atmosphere is decoupled from the solid Earth. Thus, it is difficult for the seismic wave energy inside the Earth to propagate into the atmosphere, and atmospheric pressure wave signals excited by earthquakes are unlikely ...

From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Acoustic-gravity wave triad resonance in compressible flow: a dynamical systems approach

Journal of Fluid Mechanics
The classical water-wave theory often neglects water compressibility effects, assuming acoustic and gravity waves propagate independently due to their disparate spatial and temporal scales.

Cereal Biomass Valorization for Functional Food Ingredients: Fractionation and Circular Biorefinery Strategies

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food processing must transition toward resource‐efficient systems that operate within planetary boundaries. Cereals, as climate‐resilient staples, offer strong potential to valorize nutrient‐rich fractions. Zero‐waste biorefinery concepts and green fractionation technologies, integrated with structure–function principles, enable the conversion

Deep ocean circulation by acoustic-gravity waves: from snowball to greenhouse earth

Acoustic-gravity waves are compression-type waves propagating with amplitudes governed by the restoring force of gravity. They are generated, among others, by wind-wave interactions, surface waves interactions, submarine earthquakes, and movements of ...

Ionospheric response to the 2020 Samos earthquake and tsunami

Earth, Planets and Space
On 30 October 2020 at 11:51 UT, a magnitude 7.0 earthquake occurred in the Dodecanese sea (37.84°N, 26.81°E, 10 km depth) and generated a tsunami with an observed run-up of more than 1 m on the Turkish coasts. Both the earthquake and the tsunami produced

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

Altitude Dependence of Quasi‐Static Potential Drop: The Effect of Ionospheric Protons

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Using an improved kinetic model that incorporates cold ionospheric protons and oxygen ions, we investigate the factors controlling the altitude range of the auroral acceleration region (AAR). In this model, parallel electric fields are generated via Dispersive Alfven Wave‐ Modified electron Acoustic Wave (DAW‐MEAW) coupling and sustained by ...

Acoustic-gravity modons in the atmosphere

Annales Geophysicae
It is shown that the equations governing low-frequency acoustic-gravity waves in a stable stratified atmosphere can have localized dipole-vortex solutions (modons).
