What does this ranking count?

Each interministerial order recognizing a state of natural disaster for one event and one type of hazard (flood, mudslide, drought, ground movement, storm…) counts as one, since 1982. Recognition allows insured losses to be compensated. The count also depends on the requests filed by each commune, so on its own it does not measure exposure to hazards, which Géorisques details address by address.
