An integration between geomorphological maps constructed in the Bay of Naples and in the Cilento offshore is herein presented, aimed at showing a more complete geomorphological framework of these two sectors of the Eastern Tyrrhenian margin. Both geomorphological maps have been constructed in a GIS environment. The landforms recognized in the Bay of Naples have been compiled based on onshore and offshore literature data and have been geo-referenced in a GIS environment. The landforms recognized in the Cilento offshore have been reported after reviewing the results of the geological sheet n. 502 "Agropoli" at the 1:50,000 scale. The integration between the geomorphological maps constructed in the Bay of Naples and in the Cilento offshore has highlighted that important differences exist between these two sectors of the Eastern Tyrrhenian margin. While the geological evolution of the Cilento offshore has been mainly controlled by the sedimentary processes, the Bay of Naples has been dominated by the volcanic processes, which have strongly influenced the geomorphological setting of this area, both onshore and offshore. These maps represent a useful tool for planning marine hazards in the Bay of Naples and of the Cilento offshore. Based on the obtained results the marine hazard is high in the Bay of Naples at southern Ischia, in correspondence of the Naples canyons, and at the southern slope of Sorrento-Capri. On the contrary, the marine hazard is low in the Cilento offshore, where the mapped landforms have shown normal sedimentary processes.

Abstract
An integration between geomorphological maps constructed in the Bay of Naples and in the Cilento offshore is herein presented, aimed at showing a more complete geomorphological framework of these two sectors of the Eastern Tyrrhenian margin. Both geomorphological maps have been constructed in a GIS environment. The landforms recognized in the Bay of Naples have been compiled based on onshore and offshore literature data and have been geo-referenced in a GIS environment. The landforms recognized in the Cilento offshore have been reported after reviewing the results of the geological sheet n. 502 "Agropoli" at the 1:50,000 scale. The integration between the geomorphological maps constructed in the Bay of Naples and in the Cilento offshore has highlighted that important differences exist between these two sectors of the Eastern Tyrrhenian margin. While the geological evolution of the Cilento offshore has been mainly controlled by the sedimentary processes, the Bay of Naples has been dominated by the volcanic processes, which have strongly influenced the geomorphological setting of this area, both onshore and offshore. These maps represent a useful tool for planning marine hazards in the Bay of Naples and of the Cilento offshore. Based on the obtained results the marine hazard is high in the Bay of Naples at southern Ischia, in correspondence of the Naples canyons, and at the southern slope of Sorrento-Capri. On the contrary, the marine hazard is low in the Cilento offshore, where the mapped landforms have shown normal sedimentary processes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
