In the violent
Plinian eruption, there is a larger quantity of pyroclastic flow with pumice and the eruption collapses the top of the cone resulting in a caldera.
"
Plinian volcanic eruptions are a dominant driver of naturally forced climate change during the last millennium," relates Colose.

plinian eruptions of 1912 at Novarupta, Katmai National Park, Alaska," Bulletin of Volcanology, vol.
Additionally, within the acquisition agreement the company will appoint Bradford Mills as executive vice chairman and Anton Mauve as managing director of the company, both having been principals of
Plinian Capital Limited which has acted as operator of CMC Guernsey.
In this stop on the upper flanks of NRV outcrops the tephra deposits related mainly with the late Pleistocene--Holocene
Plinian to sub-Plinian activity in NRV (~ 11,000 yr.
He explores the interplay between an aestheticizing, "
Plinian" art history that sees art as an autonomous production of the individual artist, and more recent, historically informed approaches that concentrate on the consumer and the ways in which an artist's individual style rests on historically contingent circumstances.

Plinian eruption of Askja volcano in Iceland.
79--which killed his uncle, Pliny the Elder, the author--ironically--of the greatest scientific treatise of the classical era--wrote, "We saw the sea sucked away, apparently forced back by the earthquake; at any rate, it receded from the shore so that quantities of sea creatures were left stranded on dry sand." His description of the eruption's mushroom-shaped ash column--like an "umbrella pine"--holds valid today, as volcanologists still call such an ash cloud a pino, and any explosive eruption is called, in his honor, a
plinian.
While it hardly represents the brief treatment promised by Landino at the beginning of the chiosa, it nonetheless provides further confirmation of his didactic and digressive tendencies, encylopedism, use of
Plinian natural lore, and interest in making science available in the vernacular.
An important distinction is made between units produced by large
plinian and sub-plinian volcanic events and the process known as tephra accretion (Neall 1977).
(344-49) As before, Othello alludes here to European (
Plinian) commonplaces of the exotic.
