From Wikipedia, the free encyclopedia

Examples of explosive VEI-7 eruptions. Such eruptions release a volume of at least 100 cubic kilometers with devastating longterm effects on the surrounding area and profound shortterm effects on global climate.

For smaller eruptions that have erupted at least 10 cubic kilometers at a time, see Category:VEI-6 Eruptions.

For larger eruptions that have erupted at least 1000 cubic kilometers at a time, see Category:VEI-8 Eruptions.

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.

The Minoan eruption of Thera in the middle of the second millennium BC may have been VEI-7, but may have been just shy of the 100 cubic kilometers required.

Lake Taupo also had a VEI-7 eruption in 180, but it was not directly observed in written record. It was indirectly observed via ash clouds that reached both the Roman Empire and Han Dynasty China.
