The volcanic explosivity index (VEI) an estimate of explosive magnitude for historical volcanism
Journal of Geophysical Research: Oceans, 1982Knowledge 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

Non-explosive silicic volcanism
Nature, 1986Silicic magma can erupt quietly, as vapour-poor lava, despite petrological evidence that it once contained ample dissolved water to drive violent venting of tephra. Non-explosive eruption of lava appears to result from rapid, sub-surface gas release from magma ascending as a permeable foam. The degassed foam then collapses during extrusion.

Vaporization Waves in Explosive Volcanism
Nature, 1971THE necessary conditions for explosive volcanism cannot yet be stated, but certain tentative requirements emerge from the study of pyroclastic rocks and from the observation of erupted magmas. In the first quantitative report on the mechanics of ash formation, Verhoogen1 required that the magma have high viscosity and a large gas content. More recently

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

Explosive volcanism: Observations and processes
2022Wherever 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 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.

Natural Cyclicity of Explosive Volcanism
Вестник Рязанского государственного университета имени С.А. Есенина, 2022Рассмотрены 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, 1933The 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.
