The present work aims at identifying the location of recent debris-flow-dominated alluvial fans at a regional scale in Calabria (southern Italy). Here, alluvial fans widely occur as both tributary junction and mountain front types and represent a potential hazard to human settlements and transportation links near or on them. The alluvial fans inventory map at 1:250,000 scale was obtained by means of a stereoscopic interpretation of aerial photos shot in 1954–1955. To establish the activity of

Subsequently, the activity of the alluvial fans over the last 60 years has been divided into four classes. A total of 1170 alluvial fans have been mapped, 545 (46.58%) of which have been active over the last 60 years. The alluvial fans with a length from apex to toe
