79

On 24 August 79, the Tenth Doctor caused Mount Vesuvius to erupt, killing thousands of Pompeii's residents as well as the invading Pyroviles. Thanks to Donna's pleading, he saved one of the town's families, the Caecilius family. (TV: The Fires of Pompeii) The Seventh Doctor and Melanie Bush likewise arrived in Pompeii and witnessed the eruption of Mount Vesuvius, but the Doctor remained completely ignorant of the presence of both his future self and the Pyroviles in the city. (AUDIO: The Fires of Vulcan) Multiple visits were made by the 51st century ex-Time Agent and con artist Jack Harkness. (TV: The Empty Child / The Doctor Dances)

A time disruption briefly changed history so that Vesuvius took longer to erupt, allowing the city's populace to evacuate in their boats. (PROSE: The Algebra of Ice)
