Fig. 8. RSL reconstructions in southwestern Sardinia (#8), north-central Latium (#9), Gulf of Gaeta (#10) and Salerno Bay (#11). Index points (boxes) are plotted as calibrated age against
change in sea level relative to the present. Limiting points are plotted as terrestrial or marine horizontal lines. Dimensions of boxes and lines for each point based on 2s elevation and age
errors. The relative sea-level data are compared to a prediction (red line with minimum and maximum errors) from the SELEN model (see Section 4). Red dots represent the approximate
location of RSL data-points. Th, Tharros, Mi, Is Mistras, Or, Gulf of Oristano, Pi, Piscinni Bay and Malfatano Cape; St, Sant’Antioco; Ca, Cagliari; No, Nora. Cv, Civitavecchia; Sm, Santa
