The main cone of Vesuvius and the cliff of Monte Somma's caldera separated by the Inferno and Gigante valley. Vesuvius is a "humpbacked" peak, consisting of a large cone (Gran Cono) partially encircled by the steep rim of a summit caldera caused by the collapse of an earlier (and originally much higher) structure called Mount Somma.

Mount Vesuvius violently spewed forth a cloud of super-heated tephra and gases to a height of 33 km (21 mi), ejecting molten rock, pulverized pumice and hot ash at 1.5 million tons per second, ultimately releasing 100,000 times the thermal energy of the atomic bombings of Hiroshima and Nagasaki.
The Vesuvius red zone (Italian: zona rossa del Vesuvio) is the area designated to be quickly evacuated within a few days in the case of an eruption of Mount Vesuvius. [1]

[ 1 ] [ 2 ] [ 3 ] A minor eruption was recorded in 1500 by a singular source from Ambrosio Leone, however this event was likely caused due to a phreatic event, increased fumarolic activity ...
These bubbles agglutinate and once they reach a certain size (about 75% of the total volume of the magma conduit) they explode. The narrow confines of the conduit force the gases and associated magma up, forming an eruptive column. Eruption velocity is controlled by the gas contents of the column, and low-strength surface rocks commonly crack ...
