Used for any type of object (although preferably areas) that is located on a zone prone to hazards. The determination of such zones can be done in many ways:

  • Geomorphological analysis
  • Analysis of past events (registries...)
  • Local knowledge ("There is a landslide on this zone almost every Spring", "My father told me that there has been a huge avalanche that destroyed a few houses here when he was a child"...).
  • ...

Of course, it is extremely difficult to precisely determine the spatial extent of a potential hazard, but a general delineation is often sufficient for general DRR (Disaster Risk Reduction) activities.

Note that the main aim of this tag is to support Disaster Risk Reduction programs and activities in technically less advanced countries, where such information is not systematically available.
