Areas subject to sinkholes - ISPRA Environmental Indicators Data base
Sinkholes are chasms that suddenly open in the ground, with diameters that can reach hundreds of meters.
Depending on the causes from which they originate, they are divided into sinkholes of natural origin and sinkholes of anthropogenic origin.
According to ISPRA data, the regions most exposed to natural sinkholes include Friuli-Venezia Giulia, Lazio, Puglia, Campania and Toscana, while cities such as Rome, Naples and Cagliari are particularly vulnerable to sinkholes caused by human activities.
