Natural risk zones:
Categorisation of land according to estimated/ registered anticipated risk
for natural hazards; floods, landslides, avalanches, forest fires etc.
Methods for assessing risk zones is based on a variety of data. Important data
include physical data about terrain, vegetation, climate, geology.
European projects on natural risks, forest fires etc. Only high-level
harmonisation. The data are risk susceptibility zones.
Example data sets
• Flooding
• Land slides
• Snow slide-avalanches:
• Forest, bush, grassland
• Earthquakes:
• Volcano eruptions
Technological risk zones:
Categorising areas according to their vicinity to locations producing,
storing, transporting potential artificial/ technological hazards, chemical
industry, nuclear power plants etc.
Seveso II Directive describes certain kinds of technological risks. Extension of
fields covered by the Directive is proposed. Used in land use planning to
decrease population exposed to risks.
Technological and natural disasters :
Location of actual events, site of occurrence, cause, effects, e.g. the
European forest fire mapping projec
Important in disaster operations, assessment of risks and climate change, and
follow up actions in areas affected.
