Italy: where the flood risk actually sits

These are Italy's official flood hazard zones — P1 (low), P2 (medium), P3 (high probability) — mapped by river basin authorities and mosaicked nationally by ISPRA under the EU Floods Directive (2007/60/EC). Toggle the layers to compare hazard scenarios. The most exposed zones sit disproportionately in the Po valley — Lombardy, Veneto, Emilia-Romagna — the same region that generates roughly 55% of Italy's GDP.

P1 — low probability
P2 — medium probability
P3 — high probability (frequent)

Use the layer control (top right of the map) to toggle each hazard scenario on or off.

This is the same underlying pattern the country cards on the homepage describe in numbers: Italy has the highest natural-hazard insurance gap of the four countries covered (78%) and no mandatory coverage system, while its most exposed flood zones concentrate in its economic core rather than its periphery.
