The volcanic explosivity index (VEI) is a scale used to measure the size of explosive volcanic eruptions. It was devised by Christopher G. Newhall of the United States Geological Survey and Stephen Self in 1982.
This article is a list of historical volcanic eruptions of approximately magnitude 6 or more on the Volcanic Explosivity Index (VEI) or equivalent sulfur dioxide emission during the Holocene, and Pleistocene eruptions of the Decade Volcanoes (Avachinsky–Koryaksky, Kamchatka; Colima, Trans-Mexican Volcanic Belt; Mount Etna, Sicily; Galeras ...
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.
This timeline of volcanism on Earth includes a list of major volcanic eruptions of approximately at least magnitude 6 on the Volcanic explosivity index (VEI) or equivalent sulfur dioxide emission during the Quaternary period (from 2.58 Mya to the present). Other volcanic eruptions are also listed.
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.
The inclusion criteria here only covers entries with a Volcanic explosivity index (VEI) of 5 or greater. The given values for events in the Miocene epoch sometimes lack references, and are given as VEI-equivalent, as an estimate of the erupted tephra volume.
The Campanian Ignimbrite eruption (CI, also CI eruption) was a major volcanic eruption in the Mediterranean during the late Quaternary, classified 7 on the Volcanic Explosivity Index (VEI).
In the criteria of Volcanic Explosivity Index, recognizing an eruption as ultra-Plinian would make it at least VEI-5 or higher. [ 9 ] The threshold for ultra-Plinian eruptions is defined by an eruptive column height of 45 km (28 mi), [ 10 ] or 41 km (25 mi) more recently. [ 11 ]
