**1. Introduction**

Somma-Vesuvius volcano has shaded many volcanological avenues since the two letters of Pliny the Younger to Tacitus [1]. He described the dynamism of the Pompeii Plinian eruption. Since then, Somma-Vesuvius has utterly been studied by many earth scientists worldwide who have increased the knowledge of the volcano. Today, Somma-Vesuvius is the best studied and monitored volcano in the world. The volcano is very much known about its volcano stratigraphy and by the chemistry of the volcanic products as well as by the physical architecture of the volcano. Anyhow, it is little known how the population feel about the impact of the hazardous volcanic eruptions [2–6]. To envisage different volcanic scenarios is a must in order to help the population around Vesuvius to better understand the type of next eruption that will impact on the region nearby Somma-Vesuvius. A simplified scheme of AD 79 eruption related to all the volcanic activity of a such destructive volcano can shed

light and ease the Neapolitan population that live around Somma-Vesuvius in case of future Plinian eruption. This simplified review on an open access international journal can also be available for students and general population and help high school students to understand the hazard of Somma-Vesuvius and to discuss this issue with their family.
