**2. Volcanology at the centre of the people**

Finally, Paone [12] shows how Somma-Vesuvius works with an outline on the state of the volcano. Somma-Vesuvius is a quiescent stratovolcano with a probability of Plinian-style volcanic reactivation. Its stratigraphy is well known in the last 40 ka BP. The volcanic products that are part of the Somma caldera are poorly studied. Conversely, younger products have been deeply studied together with the AD 79 Plinian eruption. The impact of a Plinian eruption has been studied and summarized. A simplified scheme is presented from what we can understand the volcanic hazard and risk that the volcano poses to the greater Neapolitan population. In the last 40 years, the demography around the Somma-Vesuvius volcano has increased; consequently, the volcanic risk has increased. It would seem that the Italian Civil Protection (ICP) has not influenced the population and the Italian authority with their massive work around Somma-Vesuvius (red zone). People still continue to build houses. Nowadays, the Somma-Vesuvius volcano does not seem to threaten people, or the people that live around Vesuvius are not afraid of the volcano. But as it is usual just in this moment that the work done and to be done must be speared to all Neapolitan people, working in the school to reach the family. People around Somma-Vesuvius tend to neglect the volcanic risk appearing around Vesuvius. So ICP, all must be much more attend about the behaviour of this Hazardous volcano.

Finally, any active or quiescent volcano must be studied by volcanologist very carefully and all the information must be passed to the people living around it in order to have the people at the centre of the Volcanology.
