The Impact of the Hunga Tonga Volcanic Eruption on Earth's Temperature

Journal of Basic & Applied Sciences
In January 2020, we published a paper [1] showing that the Intergovernmental Panel on Climate Change (IPCC) claimed that Earth’s temperature would reach 1.5 °C above pre-industrial days by 2030. At the same time, those who study the Sun, such as Valentina Zharkov, indicated that by 2030, the Earth's temperature would be much lower and close to pre ...

Atmospheric and environmental effects of the 1783-1784 Laki eruption: A review and reassessment [PDF]

, 2003
The 1783–1784 Laki flood lava eruption in Iceland emitted ∼122 megatons (Mt) SO2 into the atmosphere and maintained a sulfuric aerosol veil that hung over the Northern Hemisphere for >5 months. The eruption columns extended to 9–13 km and released ∼95

Unusual Variation in Nitric Oxide Radiative Flux and Neutral Density Over Hunga‐Tonga Region Caused by the Volcanic Eruption

Geophysical Research Letters
Large‐scale volcanic eruptions, such as the Hunga‐Tonga volcanic eruption that occurred in 2022, can impact the atmospheric structure and dynamics in a highly complex way.

Multiwave Structure of Traveling Ionospheric Disturbances Excited by the Tonga Volcanic Eruptions Observed by a Dense GNSS Network in China

Space Weather, 2023
We used dense global navigation satellite system data from China to track the propagation of traveling ionospheric disturbances (TIDs) triggered by the 2022 January 15 Tonga volcanic eruption. We identified two TIDs originating from the eruption.

Attributing the Stratospheric Impacts From the Water‐Rich Explosive Hunga Volcanic Eruption of 2022

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The January 2022 Hunga volcanic eruption injected an unprecedented ∼150 Tg of water vapor (H2 ${\mathrm{H}}_{2}$O) and ∼0.4 Tg of sulfur dioxide (SO2 ${\text{SO}}_{2}$) into the stratosphere. Observational studies confirm that this perturbation triggered significant changes in stratospheric composition and dynamics.

Communication Satellite Access in the Pacific: Current Status and Implications for Policy

Asia &the Pacific Policy Studies, Volume 13, Issue 3, September 2026.
ABSTRACT This article focuses on communication satellite access in the Pacific Island countries. While satellites can provide telecommunication and internet access, very little academic literature is available about access to satellite communication technology in the Pacific region or policy responses to it.

Medium‐Scale Traveling Ionospheric Disturbances Induced by Secondary Gravity Waves Associated With Record‐Breaking Heavy Rainfall in August 2021 Over Kyushu, Japan

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract This study reconstructs a multistep gravity wave (GW) pathway, from the generation of primary GWs by deep convection in the troposphere to the generation of secondary GWs that drive semi‐concentric medium‐scale traveling ionospheric disturbances (MSTIDs) in the ionosphere, during the record‐breaking heavy rainfall over Kyushu, Japan, in August

The impact of the 1783–1784 AD Laki eruption on global aerosol formation processes and cloud condensation nuclei [PDF]

, 2010
The 1783–1784 AD Laki flood lava eruption commenced on 8 June 1783 and released 122 Tg of sulphur dioxide gas over the course of 8 months into the upper troposphere and lower stratosphere above Iceland. Previous studies have examined the impact of the

Simulation study of atmosphere–ionosphere variations driven by the eruption of Hunga Tonga-Hunga Ha’apai on 15 January 2022

Earth, Planets and Space
The volcano of Hunga Tonga-Hunga Ha’apai in Tonga erupted on 15 January 2022, generating severe disturbances in the atmosphere and the ionosphere. This event provided us with large amount of data of the atmosphere and the ionosphere, and various kinds of

Diffusion Height and Order of Sulfur Dioxide and Bromine Monoxide Plumes from the Hunga Tonga–Hunga Ha’apai Volcanic Eruption

Remote Sensing, 2023
A violent volcanic eruption attracting considerable attention occurred on 15 January 2022 near the South Pacific island nation of Tonga. To investigate its environmental impact, we retrieved the sulfur dioxide (SO2) and bromine monoxide (BrO) vertical ...
