Regional transportation and influence of atmospheric aerosols triggered by Tonga volcanic eruption

Environmental Pollution, 2023
A cataclysmic submarine volcano at Hunga Tonga-HungaHa'apai (HTHH) near Tonga, erupted violently on 15 January 2022, which injected a plume of ash cloud soaring into the upper atmosphere. In this study, we examined the regional transportation and potential influence of atmospheric aerosols triggered by HTHH volcano, based on active and passive ...

The global reach of the 2022 Tonga volcanic eruption

2022
<p>The Tonga volcanic eruption of 15 January 2022 generated tsunami waves that impacted the entire Global Ocean as far away as 18,000 km from the source in the tropical Pacific Ocean. A defining characteristic of the tsunami was the dual forcing mechanism that sent oceanic waves radiating outward from the source at the longwave speed and ...

Tonga’s National EMT Response to the Hunga-Tonga Hunga-Ha’apai Volcanic Eruption and Tsunami

Prehospital and Disaster Medicine, 2022
Background/Introduction:The Tonga Emergency Medical Assistance Team (TEMAT) responded to the Hunga Tonga-Hunga Ha’apai (HTHH) volcano and tsunami in early 2022. The HTHH volcano erupted violently on January 15, 2022 triggering a tsunami that struck many of Tonga’s 169 islands.1 84% of the country’s population was affected.2 Tonga’s undersea internet ...

Signature of Tonga Volcanic Eruption in the ionosphere over South America

2022
On January 15, 2022, we observed various unusual atmospheric wave events over the South American sector: Atmospheric pressure waves (Lamb mode) around 12:30 to 17:30 UT, Tsunamis along the Chile coast at around 17:00 to 19:00 UT, and related ionospheric disturbances between 11:30 and 20:00 UT. We understand that these events were generated by the Tonga

A dense observation of the meteotsunami wavefield of the 2022 Hunga Tonga volcanic eruption

2022
Meteotsunamis triggered by atmospheric disturbances of Lamb waves due to the 2022 Hunga Tonga volcanic eruption were observed in coastal areas surrounding the Pacific Ocean. However, the spatio-temporal evolution of the meteotsunami wavefield remain elusive due to the lack of geophysical observations in the ocean.

A meteotsunami in the north Indian Ocean triggered by Hunga Tonga volcanic eruption.

2023
The Hunga Tonga Volcano in the southwest Pacific islands of Tonga erupted in January 2022. The massive explosion resulted in the generation of Lamb waves that propagated globally with a speed of ~ 300m/s and generated a tsunami that has affected numerous Pacific countries.

Volcanic Eruption at Metis Shoal, Tonga, 1967-1968: Description and Petrology

Smithsonian Contributions to the Earth Sciences, 1970
The 1967-1968 eruption of Metis Shoal, Tonga, was evidentially similar to the frequent shallow submarine eruptions of the inner island arc of Tonga. The eruption began about 10 December 1967, and an island eventually emerged; by 19 February 1968, the island had been eroded to beneath wave base.

Physical Mechanisms of Volcanic Earthquakes After the 2022 Hunga Eruption, Tonga

Terra Nova
ABSTRACTThe climactic eruption of the Hunga volcano in Tonga in 2022 profoundly impacted the Earth's system. Subsequent to the eruption, ongoing seismic activity in the vicinity raised concerns among local communities about volcanic hazards, highlighting gaps in understanding post‐eruption processes.
