Mass-transport deposits (MTDs), olistostromes and related soft-sediment deformation structures represent significant components of the geological architecture of both modern and ancient continental margins, including active, passive and hybrid margin types (Dilek and Rowland, 1993; Stoker et al., 1998; Dilek and Robinson, 2003; Lamarche et al., 2008; Madon, 2010; Ratzov et al., 2010; Anma et al., 2011; Pini et al., 2012; Festa et al., 2013), and are commonly associated with earthquakes and tsunamis (eg, Tappin et al., 2008). These tsunamic events adversely affected the human populations, engineering infrastructures and global economy, and inflicted severe and locally irrecoverable damages on the coastal ecosystems (eg, Yamada et al., 2012 and references therein).Improving our understanding of the mechanisms and processes of slope failure and MTD development, their spatial and temporal relationships with seismic events, and the dynamic equilibrium of active, passive and hybrid continental margins is one of the most urgent and challenging tasks faced by modern Earth science. To that end, a key approach to increase our scientific knowledge on these topics of both great scientific and societal importance is a comparative analysis of modern and ancient examples of MTDs, chaotic rock bodies and olistostromes (sensu Flores, 1955 or “sedimentary mélanges” sensu Bettelli and Panini, 1985; Festa et al., 2012), and the processes of their formation
