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.

Influences of sea level changes and volcanic eruptions on Holocene vegetation in Tonga [PDF]
Biotropica, 2023 Here, we investigate Mid- to Late-Holocene vegetation changes in low-lying coastal areas in Tonga and how changing sea levels and recurrent volcanic eruptions have influenced vegetation dynamics on four islands of the Tongan archipelago (South Pacific).
