ABSTRACT
The Archaeological Park of the Roman Thermae of Baia includes a large portion of the buildings built up during the Roman age. They attest not only to the extraordinary rich commission of the Baia buildings, but also to the refined architectural technique of local workmanship. This area is located on the western side of the Phlegrean Fields area, affected by the intense bradyseism activity, an exceptional example of volcanic-related subsidence with unrest cycles characterized by a slow uplift and sinking of the caldera floor. Due to the unusual setting of the cliff, in order to maintain the terracing of the slope and to prevent soil erosion and small collapse events, considerable control has always been needed. A detail InSAR analysis (focused mainly on Sentinel-1 data) was carried out in order to highlight most recent ground displacements. Obtained results clearly show a ground uplifting in the investigated time interval, with displacement rate up to 50 mm/yr.
