It measures the magnitude of an eruption based on how much debris is ejected. It goes from one to eight, one being the quietest and eight being the worst.
VEI 1) Not too bad. A few rumbles and some ash/lava
VEI 2) A little worse. More ashfall and more hazards
VEI 3) Destructive. Explosions heard far away and ashfall reaches great distances
VEI 4) Serious. Hot gasses, ash, and pumice forms deadly avalanches that travel tens of miles flattening and cooking everything (pyroclastic flows).
VEI 5) Horrible destruction. Pyroclastic flows and ashfall cause major disruptions in local and distant areas.
VEI 6) Devastating. Property completely destroyed. Eruptions consist of a series of detonations followed by powerful shockwaves.
VEI 7) Land is sterilized for tens of miles around. Shockwaves can blow down trees and poorly built homes. Pressurized air waves shatter people's eardrums and blow in windows.
VEI 8) Complete devastation. Usually called super-eruptions, these have a similar effect of asteroid impacts. Sulfur dioxide from the eruption circles the planet and causes decades of nuclear winters, resulting in famine and world-wide riots.
Mauna Kea does that have a recorded VEI, as it has not erupted for over 4500 years, but is said to be around VEI-2
VEI is the volcanic explosivity index. It rates the severity of explosive volcanic eruptions based on the volume of material ejected and the height of the eruption plume. The scale ranges from VEI 0, indicating a non-explosive eruption, to VEI 8, indicating a super eruption. Each step up the scale represents a tenfold increase in the size of the eruption.
A supervolcano typically has a Volcanic Explosivity Index (VEI) of 8, which is the highest level on the scale. This VEI indicates an eruption that releases more than 1,000 cubic kilometers of material, causing widespread devastation on a global scale. Examples of supervolcanoes include Yellowstone Caldera in the United States and Lake Toba in Indonesia.
Mount Etna, a volcano in Italy, typically ranges between VEI 0 to VEI 3, with occasional eruptions reaching up to VEI 4 level. The Volcanic Explosivity Index (VEI) is a scale used to measure the explosiveness of volcanic eruptions based on factors like volume of erupted material and plume height.
The eruption, which is still going on, is a VEI-0.

VEI stands for Volcanic Explosivity Index, which is a scale used to measure the explosiveness of volcanic eruptions based on factors such as eruption cloud height, volume of material expelled, and duration of the eruption. It ranges from 0 (non-explosive) to 8 (mega-colossal).
Volcanic explosive index is a measure of how explosive a volcanic eruption is based largely on the amount of material released. It ranges from VEI-0 for non explosive eruptions to VEI-8 for massive super eruptions.
A supervolcano typically has a Volcanic Explosivity Index (VEI) of 8, which is the highest level on the scale. This VEI indicates an eruption that releases more than 1,000 cubic kilometers of material, causing widespread devastation on a global scale.

The eruption, which is still going on, is a VEI-0.
The eruption of Eyjafjallajökull in 2010 was ranked as a 4 on the Volcanic Explosivity Index (VEI). This means it was a moderate eruption, causing disruptions to air travel in Europe due to the ash cloud it produced.
The VEI (Volcanic Explosivity Index) of the Eyjafjallajökull eruption in 2010 was 4, indicating a moderate explosive eruption with a volcanic plume rising up to 10-25 km into the atmosphere.
Mount St. Helens had a volcanic explosivity index (VEI) of 5 during its eruption on May 18, 1980. This VEI level indicates a significant explosive eruption that released a large amount of volcanic ash and caused widespread devastation in the surrounding area.
Volcanoes don't, but volcanic eruptions do. Volcanic eruptions are rated by Colcanic Explosivity Index or VEI based on the volcume of material ejected. It ranges from VEI-0 for the non-explosive eruption of lava to VEI-8 for the most violent eruptions of supervolcanoes.
Mount Pinatubo's eruption in 1991 had a Volcanic Explosivity Index (VEI) of 6. This scale measures the magnitude of volcanic eruptions based on factors like volume of erupted material, height of eruption column, and duration of eruption. A VEI 6 is classified as a "colossal" eruption.
