Charge structure in volcanic plumes: a comparison of plume properties predicted by an integral plume model to observations of volcanic lightning during the 2010 eruption of Eyjafjallajökull, Iceland [PDF]

, 2014
Observations of volcanic lightning made using a lightning mapping array during the 2010 eruption of Eyjafjallajökull allow the trajectory and growth of the volcanic plume to be determined.

Network Analysis Measuring the Impact of Volcanic Eruptions

Atmosphere, 2022
Volcanoes can be extremely damaging to the environment, human society, and also impact climate change. During volcanic eruption, massive amounts of gases and dust particles are thrown into the atmosphere and propagated instantaneously by the ...

Tonga volcanic eruption and tsunami, January 2022: globally the most significant opportunity to observe an explosive and tsunamigenic submarine eruption since AD 1883 Krakatau

Geoscience Letters, 2022
January 2022 witnessed the violent eruption of Hunga Tonga–Hunga Haʻapai submarine volcano in the South Pacific. With a volcanic explosivity index possibly equivalent to VEI 5, this represents the largest seaborne eruption for nearly one and a half ...

Large‐Scale Disturbances in the Upper Thermosphere Induced by the 2022 Tonga Volcanic Eruption

Geophysical Research Letters, 2023
AbstractThe effects of volcanic eruptions on the ionosphere have been well studied, however, evidence for the anticipated upper atmospheric neutral variations and their exact extents of change are rarely available. Here, we report dramatic thermospheric disturbances following the 15 January 2022 Tonga eruption.

Perturbations in stratospheric aerosol evolution due to the water-rich plume of the 2022 Hunga-Tonga eruption

Communications Earth & Environment, 2022
Large amounts of water vapour released to the stratosphere during the 2022 Hunga-Tonga hydromagmatic volcanic eruption led to decreased sulfur dioxide aerosol lifetime, increased sulfate particle size and a doubling of stratospheric aerosol optical depth,

Modeling the distribution of the volcanic aerosol cloud from the 1783–1784 Laki eruption [PDF]

, 2006
We conducted simulations of the atmospheric transformation and transport of the emissions of the 1783–1784 Laki basaltic flood lava eruption (64.10°N, 17.15°W) using the NASA Goddard Institute for Space Studies modelE climate model coupled to a sulfur ...

The near-field tsunami generated by the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano and its impact on Tongatapu, Tonga

Scientific Reports, 2022
On 15 January 2022 at 04:15 UTC, the Hunga Tonga-Hunga Ha’apai (HTHH) volcano in Tonga produced a massive eruption that triggered a transoceanic tsunami generated by the coupled ocean and atmospheric shock wave produced during the explosion.

Effect of Hunga Tonga - Hunga Ha’apai Volcanic Eruptions on Atmospheric Pressure

Coğrafi Bilimler Dergisi, 2023
The aim of this study is to examine the fluctuation in atmospheric pressure caused by the volcanic eruption of Hunga Tonga - Hunga Ha’apai volcano on January 15, 2022, at 04:14 UTC. In the study, it was predicted that the wave created by the explosion would move at a constant speed of sound and it was calculated that it would arrive in Türkiye in 13 ...
