The 79 CE eruption of Vesuvius: A lesson from the past and the need of a multidisciplinary approach for developments in volcanology

A full review of the 79 CE Plinian eruption Vesuvius is presented through a multidisciplinary approach, exploiting integration historical, stratigraphic, sedimentological, petrological, geophysical, paleoclimatic, and modelling studies dedicated to this famous devastating natural event. All have critically been reviewed integrated with original data, spanning from proximal ultradistal findings products throughout Mediterranean. The work not only combines different investigation approaches (stratigraphic, modelling), but also follows temporally eruptive depositional events, magma chamber most distal tephras. This has allowed us first compile database all those deposits, then relate (the deposits) genetic thermomechanical processes eruption), lastly better assess both local regional impacts in environment. information leads number open issues (e.g., environmental impact vs. pyroclastic current impact) that are worthy further investigations, although one best studied eruptions volcanology. structure three macro-categories, historical aspects, products, eruption. For each approach (from stratigraphy data discussed. synthesized discussion under global view eruptions, setting its dispersion as pyroclasts flowing on surface falling volcanic plume. In way, lesson past, particular well-studied Vesuvius, will be help for synchronization future developments. Lastly, various aspects hazard assessment highlighted tephra distribution points view, these large phenomena can larger than previously thought, at other active volcanoes.
