Early Evolution of the Stratospheric Aerosol Plume Following the 2022 Hunga Tonga‐Hunga Ha'apai Eruption: Lidar Observations From Reunion (21°S, 55°E)

Geophysical Research Letters, 2023
The exceptionally violent eruption of the Hunga Tonga‐Hunga Ha'apai volcano (HTHH) of 15 January 2022, in the South Pacific, was associated with a powerful blast that injected gases, steam and aerosol to unprecedentedly high altitudes.

Predicted Abundances of Carbon Compounds in Volcanic Gases on Io [PDF]

, 2004
We use chemical equilibrium calculations to model the speciation of carbon in volcanic gases on Io. The calculations cover wide temperature (500-2000 K), pressure (10^-8 to 10^+2 bars), and composition ranges (bulk O/S atomic ratios \~0 to 3), which ...

The phenomenon of gas trails in Bennett Island

Геофизический журнал, 2013
Eruptions of strong gas plumes near the Bennett Island (Arctic, Russia, De Long Archipelago) observed during 1973-1986 were studied on the base of complex field and laboratory works.

Lidar observations of pyrocumulonimbus smoke plumes in the UTLS over Tomsk (Western Siberia, Russia) from 2000 to 2017 [PDF]

Atmospheric Chemistry and Physics, 2019
Large volcanic eruptions with the volcanic explosivity index (VEI) ≥ 3 are widely known to be the strongest source of long-lived aerosol in the upper troposphere and lower stratosphere (UTLS).

Evaluating the structure and magnitude of the ash plume during the initial phase of the 2010 Eyjafjallajökull eruption using lidar observations and NAME simulations [PDF]

, 2011
The Eyjafjallajökull volcano in Iceland erupted explosively on 14 April 2010, emitting a plume of ash into the atmosphere. The ash was transported from Iceland toward Europe where mostly cloud-free skies allowed ground-based lidars at Chilbolton in ...

Melt volume at Atlantic volcanic rifted margins controlled by depth-dependent extension and mantle temperature

Nature Communications, 2021
Magmatic productivity at passive margins is controlled by mantle temperature and rifting style. The authors reveal that melt volume at rifted margins is linearly correlated with margin width and that volcanic margins may result from depth dependent ...

SO₂ emissions from basaltic eruptions, and the excess sulfur issue [PDF]

, 2004
Volcanic SO2 can affect the Earth's environment. Where no direct measurements of SO2 in the atmosphere are available, a petrologic method of assessing sulfur release from the magma must be used.
