The variable temperature of the first surge was due to interaction with the buildings. Any population remaining in structural refuges could not have escaped, as gases of incinerating temperatures surrounded the city. The lowest temperatures were in rooms under collapsed roofs. These were as low as 100 °C (212 °F), the boiling point of water. [31]
25,000 years ago: Vesuvius started forming in the Codola Plinian eruption. [18] Vesuvius was then built up by a series of lava flows, with some smaller explosive eruptions interspersed between them. By this time, the volcano was 2,000 meters (6,560 feet) tall, with the summit being 500 meters (1,640 feet) east of the current summit. [31] [32]
Historically, Vesuvius has erupted on a large scale every 300-400 years. [19] The Vesuvius Observatory has also detected bulging in the Earth’s crust; release of gasses such as sulfur dioxide, carbon dioxide, and water; and seismic activity have all been observed on multiple occasions within the past century.
