The scale is open-ended with the largest eruptions in history given a magnitude of 8. A value of 0 is given for non-explosive eruptions, defined as less than 10,000 m 3 (350,000 cu ft) of tephra ejected; and 8 representing a supervolcanic eruption that can eject 1.0 × 10 12 m 3 (240 cubic miles) of tephra and have a cloud column height of over ...
This is a list of volcanic eruptions in the 21st century with a volcanic explosivity index (VEI) of 4 or higher, and smaller eruptions that resulted in fatalities, significant damage or disruptions. The largest volcanic eruption of the 21st century is the 2022 Hunga Tonga–Hunga Haʻapai eruption and tsunami , and the deadliest are the 2018 ...
The volcanic explosivity index (commonly shortened to VEI) is a scale, from 0 to 8, for measuring the strength of eruptions but does not capture all of the properties that may be perceived to be important. It is used by the Smithsonian Institution's Global Volcanism Program in assessing the impact of historic and prehistoric lava flows.
Supervolcano – Volcano that has had an eruption with a volcanic explosivity index (VEI) of 8; Trans-Mexican Volcanic Belt – Active volcanic belt that covers central-southern Mexico; Volcanic arc – Chain of volcanoes formed above a subducting plate; Volcanic explosivity index – Predictive Qualitative scale for explosiveness of volcanic ...
Satellite images of the 15 January 2022 eruption of Hunga Tonga-Hunga Haʻapai. This is a list of volcanoes that have had large explosive eruptions during the Holocene (since about 11,650 years Before Present), with a volcanic explosivity index (VEI) of 5 or higher, or a plume height of at least 30 km.

The blast from St. Helens destroyed all organic matter and living organisms as it moved through forested areas, toppling and burying trees in its path, coming to an end near valley walls of the ...
Mackenzie, Muschalik & Broesche (2021) provided comments on the 2018 report in three separately authored sections. [4] Broesche believes that Yellowstone should be ranked higher due to the size of the volcano and the popularity of Yellowstone National Park, and Muschalik considers Mount Rainier to be just as dangerous as Kilauea due to its proximity to large population centers in Washington.
