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 ...

Stratospheric Climate Anomalies and Ozone Loss Caused by the Hunga Tonga‐Hunga Ha'apai Volcanic Eruption

Journal of Geophysical Research: Atmospheres, 2023
The Hunga Tonga‐Hunga Ha'apai (HTHH) volcanic eruption in January 2022 injected unprecedented amounts of water vapor (H2O) and a moderate amount of the aerosol precursor sulfur dioxide (SO2) into the Southern Hemisphere (SH) tropical stratosphere.

40Ar/39Ar ages of Quaternary volcanic rocks from the midwest of the Leizhou Peninsula, and their geologic significance

Dizhi lixue xuebao, 2023
Quaternary volcanic rocks are widely distributed in the Leizhou Peninsula, but the age of volcanic formation remains controversial. This study used the high-precision laser stepwise heating 40Ar/39Ar method to date the age of volcanic samples from 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 ...

The influence of the Asian summer monsoon on volcanic aerosol transport in the UTLS region

npj Climate and Atmospheric Science, 2023
This study analyses the influence of the Asian summer monsoon on volcanic aerosol transport. Realistic, altitude-resolved SO2 emissions of a middle-latitude volcanic eruption (Sarychev 2009) and a tropical volcanic eruption (Nabro 2011) were retrieved ...
