ROCKFALL HAZARD ALONG THE ANCIENT APPIA ROUTE AT THE AURUNCI PASS (ITALY): BOTH A PRESENT THREAT AND AN ORIGINAL RESOURCE IN THE LOCAL LANDSCAPE.

The Ancient Appia route crosses the Aurunci mountains at the St. Andrea Valley. On its southern side, the route track leans against a steep carbonate slope. Several rock blocks can be observed along the route track, their falling being a serious hazard to tourists safety and fruition. An hazard analysis was completed by adopting a probabilistic approach to determine rock blocks trajectories. Besides, rock failure debris were found within outstanding retaining walls, this highlighting the relationship between geological hazard and anthropogenic landscape modification.
