Danger level 1 (No or minor danger)
Danger level 2 (Moderate danger)
Danger level 3 (Considerable danger)
Danger level 4 (High danger)
Danger level 5 (Very high danger)
No danger level
Danger level 1 (No or minor danger)

Explanation of the danger level 1:

  • Earthquakes: may be perceptible
  • Meteorological phenomena: no (particular) danger, no warnings in place
  • Floods: transport disruption and damage are not normally to be expected.
  • Avalanches: generally safe conditions
  • Forest fires: small fires cannot be entirely ruled out
Danger level 2 (Moderate danger)

Explanation of the danger level 2:

  • Earthquakes: felt across a wide area, no likelihood of damage to buildings
  • Meteorological phenomena  that are normal for the respective season
  • Floods: rivers are unlikely to burst their banks and floods are unlikely but not impossible
  • Avalanches: low danger of natural avalanches
  • Forest fires: local fires can start spontaneously
Danger level 3 (Considerable danger)

Explanation of the danger level 3:

  • Earthquakes: felt across a wide area, likelihood of minor damage to buildings
  • Meteorological phenomena of an intensity slightly superior to the normal
  • Floods: rivers may burst their banks locally in exposed places and flooding may occur.
  • Avalanches: isolated exposed sectors are endangered. Some safety measures recommended in those places.
  • Forest fires: surface fires are likely
Danger level 4 (High danger)

Explanation of the danger level 4:

  • Earthquakes: felt strongly, likelihood of damage to buildings
  • Meteorological phenomena of unusual intensity
  • Floods: rivers may increasingly burst their banks and flooding may occur
  • Avalanches: many exposed sectors are endangered. Safety measures recommended in those places.
  • Forest fires: surface fires are very likely
Danger level 5 (Very high danger)

Explanation of the danger level 5:

  • Earthquakes: felt strongly, high likelihood of widespread and severe damage to buildings
  • Meteorological phenomena of very high intensity
  • Floods: rivers may burst their banks and flooding may occur in many places
  • Avalanches: acute danger. Comprehensive safety measures.
  • Forest fires: fires can start at any time

Obey in any event the orders issued by your local authorities and be prepared for exceptional measures.
