La région volcanique des Champs Phlégréens est bien connue du point de vue géo-archéologique pour ses mouvements verticaux du sol et les changements de la ligne de rivage depuis la période romaine. Nous présentons ici les résultats d'une étude géomorphologique et archéologique au large des îles de Vivara et de Procida, occupées pendant l'âge de Bronze. Cette étude a permis de mettre en évidence plusieurs paléo-lignes de rivage entre 1 et 21 m de profondeur. Le trait de côte le plus profond correspond à la période aux alentours de 7000 ans BP, tandis que ceux compris entre -18 et -10 m sont corrélés aux xviie et xve siècles avant J.-C. sur la base d'observations archéologiques. Les traces d'autres niveaux marins relatifs plus brefs ont aussi été notés à environ -8.5/-10, -5/-6, -3.5, -2.5 et -1m. Ce travail montre que la zone d'étude a subi environ 15 m de subsidence discontinue au cours des derniers 3 800 ans.
The Phlegrean Volcanic District is well known for its geoarchaeological evidence of vertical ground movements and coastal changes since the Roman period. In this paper we present the results obtained by studying the geomorphology and archaeology offshore of the Vivara and Procida islands, which were frequented by Aegean-Mycenaeans during the Bronze Age. The study allowed several palaeo-coastlines to be identified between 1 and 21 m b.s.l.. The lowest one is tentatively assigned to ca. 7000 BP, while those between -18 and -10 m are referred to date to the 18th to the 15th century B.C. on the basis of landing structures and other archaeological finds. The traces of other short-lived, relative sea-level stands have been found at about -8.5/-10, -5/-6, -3.5, -2.5 and -1 m. The study area underwent a discontinuous subsidence of about 15 m during the last 3800 years.

Abstract
The Phlegrean Volcanic District is well known for its geoarchaeological evidence of vertical ground movements and coastal changes since the Roman period. In this paper we present the results obtained by studying the geomorphology and archaeology offshore of the Vivara and Procida islands, which were frequented by Aegean-Mycenaeans during the Bronze Age. The study allowed several palaeo-coastlines to be identified between 1 and 21 m b.s.l.. The lowest one is tentatively assigned to ca. 7000 BP, while those between -18 and -10 m are referred to date to the 18th to the 15th century B.C. on the basis of landing structures and other archaeological finds. The traces of other short-lived, relative sea-level stands have been found at about -8.5/-10, -5/-6, -3.5, -2.5 and -1 m. The study area underwent a discontinuous subsidence of about 15 m during the last 3800 years.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
