Last summer, a letter penned by a group of volcanologists, including Kilburn, was published in the scientific journal Nature. It criticized the Great Pompeii Project for removing soil that could be used to learn more about the region’s past volcanic activity. “The volcanic deposits should be preserved and studied where they landed—otherwise, the information they contain about the eruption is lost,” the authors wrote.
Removing the soil, Kilburn adds, also takes away the potential to study it in the future when new technologies might be available to learn more about the deposits. But Ellis, the archaeologist, argues that despite removal of soil from atop the city, plenty remains for volcanologists to study. “As big as the excavation [at Pompeii] is, it’s still small compared with the amount of volcanic material that’s still there,” he says.
Currently, though, volcanologists don’t have permission to work within Pompeii. Ellis says that’s because rules laid out by the Italian government gave the Great Pompeii Project the rights to manage the site. Right now, its main objective is to safeguard the city’s remains from further damage after some of its ancient structures collapsed following years of exposure to the elements and poor maintenance.
Ellis explains that many scientists want access to Pompeii, making it increasingly difficult to make everyone happy. But, says Kilburn, “if we had more open collaboration, everyone would win.”
