Detailed explanation-1: -The Plinian type is an intensely violent kind of volcanic eruption exemplified by the outburst of Mount Vesuvius in Italy in 79 ce that killed the famous Roman scholar Pliny the Elder and was described in an eyewitness account by his nephew, the historian Pliny the Younger.

Detailed explanation-2: -Mt. Vesuvius has experienced numerous Plinian eruptions since the famous eruption in 79 AD. Many of these are depicted in paintings, lithographs, and engravings.

Detailed explanation-3: -Since the explosive sub-Plinian eruption of 1631, Vesuvius has erupted with both Strombolian and mixed effusive-explosive styles. For the past three centuries the volcanic activity has mainly focused inside the Somma caldera but occasionally lava issued outside it (i.e., 1760 eruption).

Detailed explanation-4: -This style of eruption is named for the eruption of Vesuvius in 79 CE which was witnessed by Pliny the Elder.

Detailed explanation-5: -A Plinian eruption is now defined as one that produces a sustained convecting plume of pyroclasts and gas rising >25km above sea level.
