TerraOverview interpretation: high flood probability (frequent floods: return period of 20 to 50 years)

The source places the point in the area of high flood hazard. Under D.Lgs. 49/2010 hazard is the probability that a flood occurs: here it is high, the scenario of frequent floods with a return period of 20 to 50 years. The class does not measure what a flood would do on the spot.
