Mount Vesuvius
Active volcano that destroyed Pompeii in 79 AD.
Mount Vesuvius is a somma–stratovolcano located on the Gulf of Naples in Campania, Italy, about 9 km east of Naples. It is one of several volcanoes forming the Campanian volcanic arc and consists of a large cone partially encircled by the steep rim of a summit caldera. Its eruption in 79 AD destroyed the Roman cities of Pompeii, Herculaneum, Oplontis, Stabiae, and other settlements, making it one of the most famous volcanic events in history.

Lore & Background
Mount Vesuvius has a long historic and literary tradition. It was considered a divinity of the Genius type at the time of the eruption of AD 79, appearing under the inscribed name Vesuvius as a serpent in decorative frescos of household shrines surviving from Pompeii. An inscription from Capua to Iovi Vesuvio indicates he was worshipped as a power of Jupiter, that is, Jupiter Vesuvius. The Romans regarded the mountain as being devoted to Hercules, and the historian Diodorus Siculus relates a tradition that Hercules passed through the region and found a place called 'the Phlegraean Plain' (Φλεγραῖον πεδίον, 'fiery'), from the mountain which of old spouted forth a huge fire.
Reader's Guide
Mount Vesuvius is significant as one of the most dangerous volcanoes in the world, marked as one of the Decade Volcanoes because 3,000,000 people live near enough to be affected by an eruption, with at least 600,000 in the danger zone. Its eruptions tend to be violent and explosive, known as Plinian eruptions, named after Pliny the Younger, whose two letters to the historian Tacitus provide the only surviving witness account of the 79 AD eruption. That eruption ejected a cloud of stones, ash, and volcanic gases to a height of 33 km, erupting molten rock and pulverised pumice at a rate of 6×10⁵ cubic metres per second. More than 1,000 people are thought to have died, though the exact toll is unknown. Since 79 AD, the volcano has erupted many times, including in 1631, six times in the 18th century, eight times in the 19th century, and in 1906, 1929, and 1944. No eruptions have occurred since 1944, and none after 79 AD were as large or destructive as the Pompeian one. Vesuvius is still regarded as an active volcano, though its current activity produces little more than sulfur-rich steam from vents at the bottom and walls of the crater.
Did You Know?
- The only surviving witness account of the 79 AD eruption consists of two letters by Pliny the Younger to the historian Tacitus.
- Vesuvius is one of several active volcanoes on Europe's mainland, with Mount Etna and Stromboli having erupted more recently.
- The volcano's slopes are scarred by lava flows, while the rest are heavily vegetated, with scrub and forests at higher altitudes and vineyards lower down.
- In 472, Vesuvian ash fell on Constantinople (Istanbul), over 1,200 kilometres away.
Frequently Asked Questions
Who is Mount Vesuvius?
Mount Vesuvius is a somma-stratovolcano rising 1,281 meters above sea level on the Gulf of Naples, roughly 9 kilometers east of the city of Naples in Campania, Italy. It forms part of the Campanian volcanic arc and features a large cone partially wrapped by the steep wall of a summit caldera.
What are Mount Vesuvius's powers/role?
Vesuvius is capable of violent explosive eruptions that can smother entire settlements in pyroclastic flows and thick ash, exactly as it did to Pompeii, Herculaneum, Oplontis, and Stabiae in 79 AD. Its dual structure of a cone inside a caldera rim gives it the potential for both explosive and effusive activity.
How does Mount Vesuvius's story end?
Vesuvius has no final chapter because it remains an active volcano; its most recent eruptive episode took place in 1944. It continues to be closely monitored by Italian authorities as a live threat rather than a relic of the past.
Why is Mount Vesuvius important?
The 79 AD eruption ranks among the best-preserved and most studied volcanic disasters in recorded history because it entombed entire Roman cities in layers of ash and pumice. That single event reshaped our understanding of both volcanic hazards and everyday Roman life.
How dangerous is Mount Vesuvius today?
At least 600,000 people live inside the immediate danger zone, and roughly 3 million more reside close enough to be impacted by a major eruption. This makes the Naples area one of the most densely populated regions in the world sitting beneath an active volcano.
