In a volcanic eruption, lava, volcanic bombs, ash, and various gases are expelled from a volcanic vent and fissure. While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major regional or even global impact, with some affecting the climate and contributing to mass extinctions.
Mount Tambora is a volcano on the island of Sumbawa in present-day Indonesia, then part of the Dutch East Indies, [2] and its 1815 eruption was the most powerful volcanic eruption in recorded human history. This eruption, with a volcanic explosivity index (VEI) of 7, ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE ...

On June 15, 1991, a rumbling Mount Pinatubo grew and grew until it exploded in the biggest volcanic eruption on Earth in 100 years. Super-pressurized, gas-charged magma burst through and a cloud ...
By contrast, the most powerful human-made explosive device ever detonated, the Tsar Bomba, had a yield of 50 megatons, whereas the eruption at La Garita was about 5,000 times more energetic. [8] The Fish Canyon eruption was the second most energetic event to have occurred on Earth since the Cretaceous–Paleogene extinction event 66 million ...
Known as a super eruption for its magnitude, the event emptied out enough volcanic material to produce the 30-by-40-mile-wide caldera. The National Park Service said the eruption covered an area ...
The 1600 eruption had a Volcanic Explosivity Index of 6 and is considered to be the only major explosive eruption of the Andes in historical time. [129] [130] It is the largest volcanic eruption in South America in recorded history [c], as well as one of the largest in the last millennium and the largest historical eruption in the Western ...
The volcanic island of Anak Krakatau in Indonesia saw an eruption on 22 December 2018 which caused a deadly tsunami, with waves surging up to five meters in height. The tsunami killed at least 437 ...
