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 ...
Volcanoes by their volcanic explosivity index (VEI). Subcategories. This category has the following 7 subcategories, out of 7 total. V. VEI-2 volcanoes (11 P)
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 ...
Modeling on an emission of 8.5 × 10 14 g of sulfur, which is 100 times the 1991 Pinatubo sulphur, volcanic winter has a maximum global mean cooling of 3.5 °C (6.3 °F) and returns gradually within the range of natural variability 5 years after the eruption. An initiation of a 1,000-year cold period or ice age is not supported by the model.
Virginia Dale, a renowned scientist with local ties, has again returned along with her ecological research team to sites catastrophically destroyed in the May 18, 1980 eruption of Mount St. Helens ...
