Following an email from Marco Olivieri from the National Institute of Geophysics and Vocanology (INGV) Italy this station name has been edited. He also confirmed that the tide gauge was sited in the vicinity of the Church Santa Maria di Porto Salvo in Naples. He suggested co-ordinates 40.8429 14.2575 for the gauge as the previous values were ~2.5km from the coast.
