The historical centre of Rome enclosed by the Aurelian Walls is built above a complex geological substratum shaped by Plio-Pleistocene sedimentary and volcanic processes (Marra & Rosa, 1995; Marra et al., 1998; Funiciello & Giordano, 2008). Subsoil lithologies distribution determined different site responses during seismic events, with damages mainly concentrated within the Tiber alluvial plain where Holocene unconsolidated terrains experienced the strongest seismic amplification (e.g. Ambrosini et al., 1986; Basili et al., 1996; Molin et al., 1986; Funiciello et al., 1995; Tertulliani & Riguzzi, 1995; Tertulliani et al., 1996; Cifelli et a., 2000; Bozzano et al., 2008).

Abstract
The historical centre of Rome enclosed by the Aurelian Walls is built above a complex geological substratum shaped by Plio-Pleistocene sedimentary and volcanic processes (Marra & Rosa, 1995; Marra et al., 1998; Funiciello & Giordano, 2008). Subsoil lithologies distribution determined different site responses during seismic events, with damages mainly concentrated within the Tiber alluvial plain where Holocene unconsolidated terrains experienced the strongest seismic amplification (e.g. Ambrosini et al., 1986; Basili et al., 1996; Molin et al., 1986; Funiciello et al., 1995; Tertulliani & Riguzzi, 1995; Tertulliani et al., 1996; Cifelli et a., 2000; Bozzano et al., 2008). Nevertheless, heavy damages caused by earthquakes were also reported for historical buildings sited above Middle Pleistocene consolidated sediments and Middle to Late Pleistocene volcanic rocks, far from the Tiber valley (Molin et al., 1995).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
