Two-stage growth of the Calabrian accretionary wedge in the Ionian Sea (Central Mediterranean): Constraints from depth‐migrated multichannel seismic data

► Relation between the pre- and post-Messinian juxtaposed wedges. ► Contact between these wedges along a major backthrust. ► The 130 km long outer Calabrian prism: a huge salt-bearing body. ► One of the fastest growing wedges (2.0 cm/year) in recent Earth history. ►~ 170 km amount of post-Messinian subduction (subduction rate 3-4 cm/year).
