More than likely, he added, such eruptions would register up to a 3 on the Volcanic Explosivity Index used to measure the force of such blasts.

The first notable eruption from Mount Cleveland was a Volcanic Explosivity Index ( VEI ) 3 Vulcanian eruption that occurred between June 10 and June 13, 1944.
43.
The latest eruption from Black Peak less than 4, 000 years ago produced an explosive eruption with a Volcanic Explosivity Index of 6 that created a caldera.
44.
It is a line of volcanic escoria cones of fissural nature lying on a west-northwest-east-southeast orientation consisting of basaltic volcanism of low explosivity.
45.
That large explosion has resulted in Tacan?being classified with a volcanic explosivity index of 4 by the Smithsonian National Museum of Natural History's Global Volcanism Program.
46.
The band is still considered to be one of the most eccentric and controversial bands in former Yugoslav music, with music, stage, energy, and explosivity.
47.
The eruption had a Volcanic Explosivity Index of 3, and involved a central vent eruption, radial fissure eruption, explosive eruption, lava flows, and a lava lake eruption.
48.
All of the eruptions listed below have produced at least of lava and tephra; for explosive eruptions, this corresponds to a Volcanic Explosivity Index ( or VEI ) of 8.
49.
Individual eruptions were often enormous, sometimes up to thousands of cubic kilometres in volume, giving them a Volcanic Explosivity Index of 8, comparable to Yellowstone Caldera and Lake Toba eruptions.

"There is a wide range of explosivity, " said geologist Willie Scott of the U . S . Geological Survey . " It's that uncertainty that makes us cautious ."
