A natural threat is a threat stemming from natural causes.

taxonomy

An agreed, common classification of natural threats does not exist. The methodical classification of all threats, drafted in the EU project VITA , probably comes closest[1]. A simplified version of the natural threats in this classification is:

  • Earth
Indented line *Shock (earthquake, volcanic energy release)
Indented line *Fast movement (Landslide)
  • Slow movement (setting, erosion)
  • Melting (volcano)
  • Water


o Precipitation (rain, snow, hail)


o Suspended in air (fog, clouds)


o High water (deluge, floods, rising ground water)


o Drought


o Solid (black ice, piling of snow, avalanche, freeze-up)


· Air


o Movement (wind)


o Material transport (e.g. sandstorm, tornado)


· Space


o Meteorites


· Electromagnetic


o Lightning


o Solar storm


· Fire


o Due to flammable materials (forest, heath)


o Due to geothermal activity (volcano)


· Biological


o Viruses (human, animal or plant disease)


o Bacteria (human, animal or plant disease)


o Fungi (human, animal or plant disease)


o Growing vegetation


Animals (plague)
