No danger level

No danger level

No evaluation
No or minor danger
Danger level 1 (No or minor danger)
Explanation of the danger level 1:
- Avalanches: no danger
- Earthquakes: potentially felt
- Floods: transport disruption and damage are not normally to be expected.
- Forest fires: small fires cannot be entirely ruled out
- Meteorological phenomena: no (particular) danger, no warnings in place
Moderate danger
Danger level 2 (Moderate danger)
Explanation of the danger level 2:
- Avalanches: very little danger
- Earthquakes: felt across a wide area, no likelihood of damage to buildings
- Floods: rivers are unlikely to burst their banks and floods are unlikely but not impossible
- Forest fires: local fires can start spontaneously
- Meteorological phenomena that are normal for the respective season
Considerable danger
Danger level 3 (Considerable danger)
Explanation of the danger level 3:
- Avalanches: exposed objects (mostly sections of transportation routes) can be endangered
- Earthquakes: felt across a wide area, likelihood of minor damage to buildings
- Floods: rivers may burst their banks locally in exposed places and flooding may occur.
- Forest fires: surface fires are likely
- Meteorological phenomena of an intensity slightly superior to the normal
High danger
Danger level 4 (High danger)
Explanation of the danger level 4:
- Avalanches: exposed objects (mostly sections of transportation routes, but in isolated cases also buildings) can be endangered
- Earthquakes: felt strongly, likelihood of severe damage to buildings
- Floods: rivers may increasingly burst their banks and flooding may occur
- Forest fires: surface fires are very likely
- Meteorological phenomena of unusual intensity
Very high danger
Danger level 5 (Very high danger)
Explanation of the danger level 5:
- Avalanches: transportation routes and settlements can be seriously endangered
- Earthquakes: felt strongly, high likelihood of widespread and severe damage to buildings
- Floods: rivers may burst their banks and flooding may occur in many places
- Forest fires: fires can start at any time
- Meteorological phenomena of very high intensity
Obey in any event the orders issued by your local authorities and be prepared for exceptional measures.
