Vesuvius Day – August 24, 2025

We commemorate the eruption of Mount Vesuvius on Vesuvius Day, which takes place on August 24 every year. Though most of us don’t know what a volcano eruption looks like, we can assume that the earth rumbles and groans as it starts to boil and roll. Volcano eruptions are also marked by the appearance of a cloud of dark ash that moves with the winds, and spreads far and wide. Finally, bright and extremely hot molten rock flows down the hill to destroy nature and human life. These are just a few of the markers of a volcano eruption. However, it is believed that the eruption of Mount Vesuvius has been one of the deadliest ones in history. On this day, we remember the lives lost to this eruption.

History of Vesuvius Day

The first major earthquake occurred in 62 A.D. This resulted was destruction across the Bay of Naples, especially Pompeii. Even though there were a few small earthquakes that occurred days before the actual eruption, no one estimated that the destruction would be so wide scale. The loss of life was massive along with the total annihilation of architecture and farmlands. Apart from Pliny the Elder, there were only a few other casualties whose names have been recorded. This included Drusilla, the Jewish princess, and Agrippa, her son. Some believe that Caesius Bassus, a poet, had also died in the eruption. By 2003, roughly 1044 casts were made from body impressions in the deposits of ash that had been discovered from Pompeii and the surrounding areas. The scattering of bones added another 100 lives lost to the eruption.

Mount Vesuvius is best known for its eruption in 79 A.D. This eruption killed over 1,000 people, and razed the cities of Pompeii, Herculaneum and other, smaller settlements to the ground. Mount Vesuvius has erupted many times since, and is regarded as one of the most dangerous volcanoes in the world due to the large population living in its proximity. Being only nine kilometers from Naples, an eruption can endanger the lives of as many as 3,000,000 people. The summit of the volcano was formed by the collapse of an earlier mountain structure, which means that the mountain used to be much higher than it is now. Today, Mount Vesuvius holds the notorious title of being one of the most dangerous volcanoes of the world despite its immense beauty.
