For smaller volcanic eruptions that have produced at least 10 km 3 (2.4 cu mi) of tephra at a time, see Category:VEI-6 eruptions. For larger volcanic eruptions that have produced at least 1,000 km 3 (240 cu mi) of tephra at a time, see Category:VEI-8 eruptions.
Scafells, Lake District, England; VEI 8; Ordovician (488.3–443.7 million years ago). Flat Landing Brook; VEI 8, A Supervolcanic eruption occurred 466 million years ago, as it erupted in one of the largest explosive volcanic eruptions known in Earth's history with a volume of ejecta at around 2,000–12,000 cubic kilometers (480–2,879 cu mi).
For larger volcanoes that have erupted at least 1,000 km 3 (240 cu mi) of tephra at a time, see Category:VEI-8 volcanoes or Category:Supervolcanoes. The only unambiguous VEI-7 eruption to have been directly observed in recorded history was Mount Tambora in 1815 and caused the Year Without a Summer in 1816.

[2] [3] This event is known as the Millennium Eruption or Tianchi eruption. [4] It is one of the most powerful volcanic eruptions in recorded history; classified at least a VEI 6. [5] [6] [7] The eruption ejected about 13–47 cubic kilometres [5] [6] [7] of magma (dense rock equivalent) and formed a caldera, which now contains a lake (Heaven ...

Volcanoes are usually not created where two tectonic plates slide past one another. In 1912–1952, in the Northern Hemisphere, studies show that within this time, winters were warmer due to no massive eruptions that had taken place. These studies demonstrate how these eruptions can cause changes within the Earth's atmosphere. [24]
