Plinian eruptions are marked by columns of gas and volcanic ash extending high into the stratosphere, the second layer of Earth's atmosphere. The key characteristics are ejection of large amount of pumice and very powerful continuous gas blast eruptions.he amount of magma erupted can be so large that the top of the volcano may collapse, resulting in a caldera. Fine ash can deposit over large areas. Plinian eruptions are often accompanied by loud noises, such as those generated by Krakatoa.
The eruption of Mount Vesuvius in 79 AD was one of the most catastrophic and infamous volcanic eruptions in European history.Historians have learned about the eruption from the eyewitness account of Pliny the Younger, a Roman administrator and poet.he year of the eruption is pinned to AD 79 (that is, the corresponding year of the Roman ab urbe condita calendar era) by references in contemporary Roman writers, a number of them apart from Pliny the Younger, and has never been seriously questioned. It is determined by the well-known events of the reign of Titus.
