The Holocene Evolution of the Volturno Coastal Plain (Northern Campania, Southern Italy): Implications for the Understanding of Subsidence Patterns

In the Mediterranean area, several alluvial coastal plains, developed after Holocene transgression, are affected by subsidence. The Volturno alluvial-coastal plain, along eastern Tyrrhenian Sea (southern Italy) is characterized subsidence rates determined through InSAR data analysis and ranging between 0 <?20 mm/year in an area of about 750 kmq across River. Inside this pattern shows sites with apparently anomalous localized To understand driving mechanisms process, a lithostratigraphic reconstruction was provided focusing on spatial distribution horizons considered weak geotechnical point view; then, map overlain spatially geological Geographic Information System (GIS) environment. highlighted major ground deformation occurring within outer boundary incised paleo-valley, corresponding to alluvial/transitional filling that overlies compaction-free Pleistocene basement. general trend, differential compaction detected thick occurrence clay peat deposits, suggesting rate registered plain due part consolidation primary settlements soft compressible soils characterize subsoil these areas, large secondary settlements.
