Ionospheric disturbances observed over China after 2022 January 15 Tonga volcano eruption
Geophysical Journal International, 2023 SUMMARY At 04:14:45 UT on 2022 January 15, a powerful eruption of the submarine Hunga Tonga–Hunga Ha'apai volcano occurred at about 30 km south of the Ha'apai Islands in the Kingdom of Tonga (at −20.55° N, −175.39° E). This eruption caused atmospheric waves that spread worldwide.

Electromagnetic ULF/ELF oscillations caused by the eruption of the Tonga volcano
Solar-Terrestrial Physics, 2023 The eruption of the Tonga volcano on January 13 and 15, 2022 and related intense lightning activity led to the excitation of a number of specific electromagnetic oscillations in different frequency ranges. We examine properties of these oscillations, using data from magnetometers of various types located in Kamchatka and in the Pacific region.
