Mount Vesuvius, Somma-stratovolcano in the Metropolitan City of Naples, Campania, Italy

Mount Vesuvius is a somma-stratovolcano: the Gran Cono, built during the AD 79 eruption, rises to 1,281 m and sits partly inside the caldera rim of the older Monte Somma, whose Punta Nasone reaches 1,132 m. The cone's slopes are scored by lava flows and gullies, with scrub and forest higher up and vineyards lower down.

The eruption in 79 destroyed Roman settlements at Pompeii and Herculaneum, preserving them under volcanic deposits for later excavation. Later major events took place in 1631 with roughly 4000 deaths, followed by activity in 1906 and the most recent recorded eruption in 1944.

Farmers at the base continue to plant vines on slopes with volcanic soil, where Lacryma Christi and Verdeca grapes grow amid layers of ash that influence each growing season. Around the crater, daily life goes on with warning systems monitoring every slight movement below the summit for decades now.

Visitors reach the summit through trails starting at the national park entrance at 1000 meters (3281 feet), requiring roughly 30 minutes of walking. Paths close during bad weather or heightened seismic activity, and guided tours offer geological insights along the route with rest points positioned at intervals.

The double structure shows Monte Somma's older crater partially enclosing the younger cone, separated by Valle del Gigante valley. This formation came from the collapse of an older caldera roughly 17000 years ago, creating a horseshoe ring still visible as the northern rim today.
