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.
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.
Volcanoes by their volcanic explosivity index (VEI). Subcategories. This category has the following 7 subcategories, out of 7 total. V. ... VEI-8 volcanoes (3 C, 20 P)
The volcanic ash fall pelted the capital and La Aurora International Airport. The National Coordinator for Disaster Reduction (CONRED) declared a red alert for the communities near the volcano and recommended the evacuation of some of them. Noti7 reporter Anibal Archila, one of the first to cover the event, was reportedly killed by volcanic debris.
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.
Technically, there's no official definition for a supervolcano structure other than it being capable of eruptions of at least a seven on the volcanic explosivity index. A volcanic eruption that ...
This is a list of notable volcanic eruptions in the 16th to 20th centuries with a Volcanic explosivity index (VEI) of 4 or higher, and smaller eruptions that resulted in significant damage or fatalities. Note that there may be uncertainties to dates with historical eruptions, and there are likely to be many large eruptions that have not been ...
This eruption, with a volcanic explosivity index (VEI) of 7, ejected 37–45 km 3 (8.9–10.8 cubic miles) of dense-rock equivalent (DRE) material into the atmosphere, [3] and was the most recent confirmed VEI-7 eruption. [4]
