The eruption of Mount Vesuvius in 79 AD devastated Pompeii, but new evidence shows that some survivors and newcomers returned to rebuild their lives in makeshift conditions. Excavations reveal modifications to buildings and signs of domestic activity, indicating a survivalist settlement. This community lived in precarious conditions, transforming the ruins into a camp-like environment. The reoccupation may have lasted until the 5th century, ending with another volcanic eruption.
