Volcanic Explosivity Index

The eruption reached a value of 3 on the Volcanic Explosivity Index.

The 2000 eruption was estimated at scale 2 on Volcanic Explosivity Index.

Both were explosive eruptions with a Volcanic Explosivity Index of at least 5.

He is the co-creator of the Volcanic explosivity index and specializes in volcanic prediction.

About 150,000 years ago, a much larger explosive eruption occurred, probably of Volcanic Explosivity Index 5.

Since then, there have been at least 65 eruptions with assumed Volcanic Explosivity Indexes of 1 or 3.

Volcanic Explosivity Index (includes list of large eruptions)

All these events were central vent eruptions with a volcanic explosivity index (VEI) of 2.

The last major eruption on Galunggung was in 1982, which had a Volcanic Explosivity Index of 4 and killed 72 people.

Mashū volcano is rated with a Volcanic Explosivity Index of 6, the second highest among large volcanoes.

This eruption was tiny compared to the volcano's major Volcanic Explosivity Index 4 eruption in 1945.

In volcanology, the Volcanic Explosivity Index is the way to measure the strength of a volcanic eruption.

The eruption had a Volcanic Explosivity Index (VEI) of at least 5.

Between 70 and 80 cubic kilometers of tephra was erupted, measuring a Volcanic Explosivity Index of 6.

On the Volcanic Explosivity Index scale, the eruption was rated a five (a Plinian eruption).

All known eruptions at the volcano have had a Volcanic Explosivity Index (VEI) of 3.

Such calderas are usually formed by large cataclysmic eruptions reaching 7 on the Volcanic Explosivity Index (described as "super-colossal").

This was Earth's most recent eruption reaching VEI-8, the highest level on the Volcanic Explosivity Index.

The event was quite small-only a Volcanic Explosivity Index 1 eruption-but it produced explosions and flames that lit up the island, along with tsunamis.

Volcanic eruptions are classified using the Volcanic Explosivity Index, or VEI.

Volcanic Explosivity Index (VEI)

In a severe Vulcanian eruption of magnitude 3 on the Volcanic Explosivity Index scale, pyroclastic flows rolled over the island.

Hala-'l Badr has a volcanic explosivity index of at least 2, meaning that it is an explosive volcano capable of producing a plume three miles high.

Tectonic earthquakes began early in January, resulting in an explosive Volcanic Explosivity Index 3 eruption later in that day.

With a Volcanic Explosivity Index of 7, it remains the largest single Holocene eruption in history of the Cascade Range.
