Which are the districts of Rome most at risk of chasms?

ISPRA in collaboration with the CNR-IGAG has launched a study project for the susceptibility to anthropogenic sinkholes since 2017. The city of Rome rises above a complex network of underground cavities, for the most part still unknown, produced by human activities, at various times, in more than two thousand years. The presence of underground cavities in particular conditions can cause the collapse of the most superficial layers of the soil with the formation of surface chasms (anthropogenic sinkholes).
