In this research, the morpho-evolutive trend of sea cliffs placed in the volcanic island of Procida was investigated. The entire perimeter of the island is bordered by cliffs, which in some cases are connected to narrow shore platforms sloping slightly towards the sea. The presence of different orders of submerged paleo-shore platforms suggests different phases of sealevel stand and related coastal response. Mapping these platforms, together with the interpretation of archaeological and geomorphological markers allowed defining the shoreline evolution of Procida Island during the last 6.5 ky. The paleo sea levels deduced from these indicators were compared with the eustatic sea-level curve proposed by [1] demonstrating that Procida coastal area was affected by an overall subsiding trend since the Mid-Holocene, which probably occurred intermittently or with variable intensity over time. By reconstructing the position of the ancient shorelines related to the three orders of platforms, the retreating rates of the cliffs bordering the area were calculated.

Abstract
In this research, the morpho-evolutive trend of sea cliffs placed in the volcanic island of Procida was investigated. The entire perimeter of the island is bordered by cliffs, which in some cases are connected to narrow shore platforms sloping slightly towards the sea. The presence of different orders of submerged paleo-shore platforms suggests different phases of sealevel stand and related coastal response. Mapping these platforms, together with the interpretation of archaeological and geomorphological markers allowed defining the shoreline evolution of Procida Island during the last 6.5 ky. The paleo sea levels deduced from these indicators were compared with the eustatic sea-level curve proposed by [1] demonstrating that Procida coastal area was affected by an overall subsiding trend since the Mid-Holocene, which probably occurred intermittently or with variable intensity over time. By reconstructing the position of the ancient shorelines related to the three orders of platforms, the retreating rates of the cliffs bordering the area were calculated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
