Potential atmospheric impact of the Toba Mega‐Eruption ∼71,000 years ago [PDF]
, 1996 An ∼6‐year long period of volcanic sulfate recorded in the GISP2 ice core about 71,100 ± 5000 years ago may provide detailed information on the atmospheric and climatic impact of the Toba mega‐eruption. Deposition of these aerosols occur at the beginning

2017 explosive eruption of Kambalny volcano
Sovremennye problemy distantsionnogo zondirovaniya Zemli iz kosmosa, 2017 Первое историческое извержение вулкана Камбальный началось 24 марта 2017 г. с мощной эмиссии пепла из вершинного кратера до 6 км над уровнем моря. По данным тефрохронологии предполагается, что сильные извержения вулкана происходили 200 (?) и 600 лет назад.

Geophysical fingerprint of the 4–11 July 2024 eruptive activity at Stromboli volcano, Italy [PDF]
Natural Hazards and Earth System SciencesParoxysmal eruptions, characterized by sudden and vigorous explosive activity, are frequent at open-vent volcanoes. Stromboli volcano, Italy, is well known for its nearly continuous degassing activity and mild explosions from the summit craters ...

Combined effusive-explosive silicic volcanism straddles the multiphase viscous-to-brittle transition
Nature Communications, 2018 Recent observations of silicic eruptions show that they can be both effusive and explosive at the same time. Here the authors use scaled experiments to demonstrate that magma in effusive eruptions will fracture during flow to the Earth’s surface ...

Major Surge Activity of Super-Active Region NOAA 10484
, 2009 We observed two surges in H-alpha from the super-active region NOAA 10484. The first surge was associated with an SF/C4.3 class flare. The second one was a major surge associated with a SF/C3.9 flare.
