“Le vulcanoclastiti di Craco” are described here as a geosite due to international importance, information value, scientific and research value. “Le vulcanoclastiti di Craco” are whitish, meters-thick volcaniclastic levels which are distinguishable as intercalated within clays (Electronic Supplementary Material Fig. 1 Repository). In particular, they are distinguishable in Masseria Galante, Fosso Bruscata and Masseria Fornella localities; in the latter, the levels are darker. The sedimentological features, petrology and geochronology of the volcaniclastic levels are detailed by Prosser et al. (2008). The levels A ghost eruption is generally explosive and is defined here as an eruption of which one may know the provenance, the age and perhaps the geodynamic context, but may not know the exact eruptive event generating associated deposits. “Le vulcanoclastiti di Craco” are volcaniclastic levels cropping out around Craco (40°23′N, 16°26′E) (Doronzo 2005), which is known to be a ghost town. The town stands on a hill ~ 400 m high immersed in the landscape of “calanchi”, which are badlands typical in Basilicata region, Italy. It is a ghost town because of a landslide occurred in 1963 (Fig. 1).
