[Frontier Letter] New aspects of the upper atmospheric disturbances caused by the explosive eruption of the 2022 Hunga Tonga–Hunga Ha’apai volcano
An explosive eruption of the Hunga Tonga–Hunga Ha’apai (Tonga) volcano occurred on 15 January 2022 generated strong shock and air pressure waves in the troposphere. Their influence globally extended from the atmosphere to ionosphere. Shinbori et al. [2023] comprehensively review the characteristics of ionospheric disturbances obtained from ground-based and satellite observation data analyses and summarizes what we know from the Tonga volcanic eruption. Further, this paper shows new scientific results of the magnetic conjugacy of 4-min ionospheric oscillations and the appearance of hectometric line spectra originating from broadcasting waves associated with the occurrence of equatorial plasma bubble after the 2022 Tonga volcanic eruption using SuperDARN HOP radar (https://cicr.isee.nagoya-u.ac.jp/hokkaido/) and Arase satellite (https://www.isas.jaxa.jp/en/missions/spacecraft/current/erg.html) observation data.
