Napoli's potential Serie A win has caused quite a stir among their passionate fan base, with some supporters jokingly planning to celebrate with a "simulation of the Vesuvius explosion."
Vesuvius is the only active volcano in continental Europe. It erupted in AD79, destroying the city of Pompeii and covering everything in its path with volcanic ash.
The national park was established in 1995 to preserve the fragile ecosystem around the volcano, whose highest peak reaches 1 277 metres.
However, the Vesuvius National Park Authority has issued a warning to fans, calling the idea dangerous and not feasible, ahead of the crucial matches on Sunday.
Park commissioner Raffaele De Luca confirmed that no authorization for any celebration on Vesuvius had been or would be issued, as the volcano is a fragile and intrinsically dangerous place.
"The Vesuvius crater is a fragile and intrinsically dangerous place," he said in the statement.
"We are all happy about Napoli's victory, which brings honour to the region and will bring great joy to its citizens, but the celebrations must be limited to what is permitted in the rules of civil life."
Napoli's victory on Sunday over Salernitana would be their first Scudetto since the days of Diego Maradona, and the National Park Authority has asked authorities responsible for public order to take appropriate measures to stop intrusions in the protected area.
