Atmosphere-Ionosphere response to the 2022 Hunga Tonga- Hunga Ha’apai volcanic eruption
Atmosphere-Ionosphere response to the 2022 Hunga Tonga- Hunga Ha’apai volcanic eruption
Session ID#: 156648
Session Description:
The 15 January 2022 Tonga underwater volcanic eruption was an unprecedented event that ejected a huge amount of energy into the atmosphere. The eruption generated strong perturbations in the atmosphere and ionosphere layers that induced Travelling Ionospheric Disturbances (TIDs) propagating for several hours, and even days, after the eruption. The eruption also generated a tsunami. The Tonga eruption was a unique event allowing us to study the Lithosphere-Atmosphere-Ionosphere coupling processes at a global level.
The session welcomes contributions on observations and modelling of the atmospheric and ionospheric disturbances induced by the Tonga eruption, encouraging multi-instrumental and multi-disciplinary approaches to the physical mechanisms behind the coupling of the different layers of the Earth system.
