Usage

This key is used to store occurrences of hazards. The project OpenHazardMap is aimed at collecting the hazard zones, i.e. the areas that are potentially prone to hazards, but it is also important to store actual events, both to corroborate the probabilistic approach of risk assessments and to start creating a worldwide database of local events.

Values

The date of occurrence must be stored.

Given that hazards often occur on the same area, multiple values can be stored. E.g. hazard_occurrence=25-01-2005,28-03-2006,01-02-2012
