(Fig. 2.18) Plinian Eruption.
Plinian eruptions are probably the most explosiveand powerful of all. They often start suddenly and unexpectedly after a long quiet period.
Plinian eruptions occur when utmost viscous magma containing a lot of gas explodes in the depth of the volcano by which the crater pipe functions as the barrel of a shotgun. An enormous gas escape shoots upwards with a very high speed whereby an enormous ash cloud comes into existence.
Ashfalls, ashflows and pyroclastic flows (nuées ardentes) predominate. Lava flows may be emitted when the eruption ends.
Plinian eruptions can blow volcanic material very high into the atmosphere which may result in climate changes. This occurred during the eruption of Pinatubo.
As the eruption ends, the whole summit area may collapse forming a caldera. Plinian eruptions are named after Pliny the Elder and Pliny the Younger. They gave us a clear view on the classic eruption of Vesuvius in AD79.
A highly explosive volcanic eruption with dense clouds of gas and
being propelled upwards for many kilometres.
Fissure eruptions
are common on the flanks of the volcano as are the destruction of the crater walls and the fragmentation of solidified lavas.

A plinian column is a gigantic cloud of ash and stuff from a volcano. It looks like the smoke from an explosion from an atomic bomb or something.
The 79 AD eruption of Mount Vesuvius, which destroyed Pompeii, was a Plinian eruption. In fact, it was the description of this eruption by Pliny the Younger that lead to the term Plinian.

No. Plinian eruptions are generally the most destructive. Vulcanian eruptions may be orders of magnitude smaller.
There is no volcano named Plinian. The term Plinian refers to a type of eruption that features a towering column of ash. There have been many such eruptions throughout history and in prehistoric times. The eruption from which the term originates was the 79 AD eruption of Mount Vesuvius in Italy, which was described in detail by Pliny the Younger.

Yes, though some would call it ultra plinian.

It has been erupting since 1922. It has a plinian eruption.
Pliny the Younger, a famous Roman author who wrote a detailed description of the eruption of Mount Vesuvius in 79 AD. It was the first detailed account of its kind.
