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.

A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time.

In the continental U.S., the most recent cataclysmic eruption of a volcano was Mount St. Helens on May 18, 1980. “Vancouver, Vancouver, this is it!” radioed U.S. Geological Survey scientist ...
The Tumalo Volcanic Center is a volcano located just east of Bend, Oregon. It started producing large eruptions around 650,000 years ago, with its first eruption reaching a 5 on the VEI scale and erupting more than 1 km 3 of magma. [12] The volcano would go on to produce at least three more voluminous eruptions.
The Centre of Volcanology and Geological Hazard Mitigation recommended that a 7 km (4.3 mi) radius around the volcano be evacuated. [75] Seven villages were affected by the eruption. [76] A larger eruption occurred on 7 November. [77] On 8 November, the volcano erupted several times, one bearing an ash plume with a height reaching 10 km (6.2 mi ...
