Plinian eruptions or Vesuvian eruptions are volcanic eruptions marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter [1] written by Pliny the Younger, after the death of his uncle Pliny the Elder.
Plinian eruptions are similar to both Vulcanian and Strombolian eruptions, except that rather than creating discrete explosive events, Plinian eruptions form sustained eruptive columns. They are also similar to Hawaiian lava fountains in that both eruptive types produce sustained eruption columns maintained by the growth of bubbles that move up ...
They concluded that the eruption unfolded in two phases, Vesuvian and Pelean, which alternated six times. [15] A first Plinian phase projected a column of volcanic debris and hot gases between 15 km (9 mi) and 30 km (19 mi) into the stratosphere. This phase lasted 18 to 20 hours and spread pumice and ashes, forming a 2.8 m (9 ft) layer to the ...
The entire Plinian eruption lasted about 20 hours and emitted 7.8 km 3 (1.9 cu mi) of magma. [26] Another attempt at reconstruction by numerical simulation shows a different Plinian process. The eruptive column rose to 44 km (27 mi), and the entire phase was completed within 4 hours with a magma volume of 23 km 3 (5.5 cu mi).
The Tierra Blanca Joven eruption is El Salvador's largest volcanic eruption in the last 10,000 years. This VEI-6 Plinian eruption occurred during the 5th century and was larger than the 1883 eruption of Krakatoa or the 1991 eruption of Mount Pinatubo, having probably been more comparable to the 1815 eruption of Mount Tambora.

The video shows August footage from Mount Dukono, an active volcano in Indonesia, not Yellowstone National Park. No evidence supports the post’s claim of a Yellowstone volcanic eruption in ...
The 2011 eruption of Grímsvötn was a Plinian eruption of Grímsvötn, Iceland's most active volcano, which caused disruption to air travel in Northwestern Europe from 22–25 May 2011. The last eruption of Grímsvötn was in 2004, [ 2 ] with the previous most powerful eruptions in 1783, 1873 and 1902.
Stunning footage has shown 100m high lava waves lap up out of an Icelandic ridge following the eruption of a volcano on the island.. The dramatic scene can be seen up to 20km away after the skies ...
