Impact and Inspiration of Tonga volcanic Eruption in 2022 [PDF]
E3S Web of Conferences, 2023 People have been puzzled by the problem of volcanic eruptions since ancient times. Because volcanic eruptions are difficult to predict accurately, if people can't take some precautions in advance, sometimes volcanic eruptions will cause great injuries ...

Rapid Volcanic Modification of the E‐Region Dynamo: ICON's First Glimpse of the Tonga Eruption
Geophysical Research Letters, 2022 The 15 January 2022 Hunga Tonga‐Hunga Ha'apai volcano eruption drove global atmospheric waves that propagated into space and impacted the ionosphere. Here we show immediate large‐scale electrodynamic effects of the eruption using observations from the ...

Generation of equatorial plasma bubble after the 2022 Tonga volcanic eruption. [PDF]
Sci Rep, 2023 Abstract Equatorial plasma bubbles are a phenomenon of plasma density depletion with small-scale density irregularities, normally observed in the equatorial ionosphere. This phenomenon, which impacts satellite-based communications, was observed in the Asia-Pacific region after the largest-on-record January 15, 2022 eruption of the ...

Ionospheric disturbances over South America related to Tonga volcanic eruption
Earth, Planets and Space, 2023 Abstract On January 15, 2022, we observed various unusual atmospheric wave events over South America: Atmospheric pressure waves (Lamb mode) around 12:30 to 17:30 UT, tsunamis along the Chilean coast at around 17:00 to 19:00 UT, and ionospheric disturbances between 11:30 and 20:00 UT.
