Abstract

Satellite radar interferometry reveals subsidence within an area of about 2 km by 2 km inside the city of Napoli, Southern Italy. The observations show a maximum (vertical) deformation of about 5-6 cm between 1992 and 1996, while the signal decreases between 1996 and 1998. The study demonstrated the high correlation between the observed deformation and the construction of a new underground railway line carried out between 1992 and 1995
