On This Day: Vesuvius Erupts

On This Day in History, August 24th, 79AD

From The History Channel

After centuries of dormancy, Mount Vesuvius erupts in southern Italy, devastating the prosperous Roman cities of Pompeii and Herculaneum and killing thousands. The cities, buried under a thick layer of volcanic material and mud, were never rebuilt and largely forgotten in the course of history. In the 18th century, Pompeii and Herculaneum were rediscovered and excavated, providing an unprecedented archaeological record of the everyday life of an ancient civilization, startlingly preserved in sudden death.

The ancient cities of Pompeii and Herculaneum thrived near the base of Mount Vesuvius at the Bay of Naples. In the time of the early Roman Empire, 20,000 people lived in Pompeii, including merchants, manufacturers, and farmers who exploited the rich soil of the region with numerous vineyards and orchards. None suspected that the black fertile earth was the legacy of earlier eruptions of Mount Vesuvius. Herculaneum was a city of 5,000 and a favorite summer destination for rich Romans. Named for the mythic hero Hercules, Herculaneum housed opulent villas and grand Roman baths. Gambling artifacts found in Herculaneum and a brothel unearthed in Pompeii attest to the decadent nature of the cities. There were smaller resort communities in the area as well, such as the quiet little town of Stabiae.At noon on August 24, 79 A.D., this pleasure and prosperity came to an end when the peak of Mount Vesuvius exploded, propelling a 10-mile mushroom cloud of ash and pumice into the stratosphere. For the next 12 hours, volcanic ash and a hail of pumice stones up to 3 inches in diameter showered Pompeii, forcing the city’s occupants to flee in terror. Some 2,000 people stayed in Pompeii, holed up in cellars or stone structures, hoping to wait out the eruption.A westerly wind protected Herculaneum from the initial stage of the eruption, but then a giant cloud of hot ash and gas surged down the western flank of Vesuvius, engulfing the city and burning or asphyxiating all who remained. This lethal cloud was followed by a flood of volcanic mud and rock, burying the city.

The people who remained in Pompeii were killed on the morning of August 25 when a cloud of toxic gas poured into the city, suffocating all that remained. A flow of rock and ash followed, collapsing roofs and walls and burying the dead.

According to Pliny the Younger’s account, the eruption lasted 18 hours. Pompeii was buried under 14 to 17 feet of ash and pumice, and the nearby seacoast was drastically changed. Herculaneum was buried under more than 60 feet of mud and volcanic material. Some residents of Pompeii later returned to dig out their destroyed homes and salvage their valuables, but many treasures were left and then forgotten.

In the 18th century, a well digger unearthed a marble statue on the site of Herculaneum. The local government excavated some other valuable art objects, but the project was abandoned. In 1748, a farmer found traces of Pompeii beneath his vineyard. Since then, excavations have gone on nearly without interruption until the present. In 1927, the Italian government resumed the excavation of Herculaneum, retrieving numerous art treasures, including bronze and marble statues and paintings.

Today, Mount Vesuvius is the only active volcano on the European mainland. Its last eruption was in 1944 and its last major eruption was in 1631. Another eruption is expected in the near future, would could be devastating for the 700,000 people who live in the “death zones” around Vesuvius.
