The volcanic explosivity index (VEI) an estimate of explosive magnitude for historical volcanism

Journal of Geophysical Research: Oceans, 1982
Knowledge of the frequencies of highly explosive, moderately explosive, and nonexplosive eruptions would be useful in a variety of volcano studies. Historical records are generally incomplete, however, and contain very little quantitative data from which explosive magnitude can be estimated. Only the largest eruptions have a complete record back to the

External ballistic of volcanic explosions [PDF]

open access: possibleBulletin Volcanologique, 1983
In order to determine the kinetic energy of an explosion it is necessary to know the initial velocities of ejected fragments. Calculations of initial velocities made earlier with few exceptions did not take into account the resistance of the air and therefore, greatly underestimated the initial velocities, and consequently the energy of the explosions.

Explosive Volcanism on Mars

2021
Explosive volcanism should be the most common style on a planet characterized by a low atmospheric pressure and by an assumed high volatile content. However, the observations of the surface of Mars show how explosive volcanism is not widespread as it should be in a planet with the above mentioned characteristics.

Explosive volcanism: Observations and processes

2022
Wherever effusive volcanism has occurred, there is usually also evidence of explosive volcanism. The boundaries between these two kinds of eruption are blurred, because even the sources of lava flows, regarded as the classic effusive landform, may exhibit explosive activity.

Explosive Volcanic Eruptions

1984
Volcanic activity takes many forms, ranging from quiet lava emissions to extremely violent and explosive bursts, many of which can be related to magma composition as discussed in Chapter 3. The kinds of eruptions can be correlated to volcano shapes and sizes, and in this chapter we explore the connection between pyroclastic systems, eruptive mechanisms

Natural Cyclicity of Explosive Volcanism

Вестник Рязанского государственного университета имени С.А. Есенина, 2022
Рассмотрены причины, факторы и закономерности пульсаций вулканической активности (для извержений с VEI не менее 5, без учета вулканов со щелочными лавами). Установлено соответствие эксплозивных событий 1650-летним (ритмы Петтерсона — Шнитникова) и 60–70-летним циклам природной динамики, порождаемым гравитационными взаимодействиями Земли со смежными ...

Volcanic explosions and overthrusts

Eos, Transactions American Geophysical Union, 1933
The problem of Heart Mountain and associated thrust sheets—On the west side of the Bighorn Basin, in the vicinity of Cody, Park County, Wyoming, Paleozoic limestones lie as isolated thrust‐masses on top of the truncated edges of Mesozoic and Early Tertiary strata (see Geologic map of Wyoming, 1:500,000, U.S. Geol. Survey, 1925). Dake (C. L.

Explosive Volcanic Eruptions

2001
During explosive volcanic eruptions, up to 1014 kg of volcanic ash may be erupted from a vent forming violent ash flows or towering eruption columns. This massive amount of material is subsequently deposited on the ground, with much of the coarser fraction of the flow being deposited within a few hundred kilometres of the volcanic edifice.

The recent explosive volcanism at Pantelleria

Geologische Rundschau, 1991
Many of the least eighty eruptions of the six silicic eruptive cycles in the last 50 ka at Pantelleria started out with explosive phases and ended with lava effusion. The pyroclastic rocks are rhyolitic in composition while the later-erupted lavas are less evolved up to trachyte probably due to the presence of a shallow and compositionally zoned magma ...
