Avalanche Size	Description	Potential Damage	Run Out	Typical Dimensions	Example
1	Small Avalanche (Sluff)	Unlikely to bury a person, except in run out zones with unfavourable terrain features (e.g. terrain traps) In extremely steep terrain, the danger of deep falls prevails the danger of burials	Stops within steep slopes.	Length: 10-30 m Volume: 100 m³
2	Medium Avalanche	May bury, injure or kill a person Size 2 corresponds to the typical skier-triggered avalanche	May reach the end of the relevant steep slope	Length: 50-200 m Volume: 1,000 m³
3	Large Avalanche	May bury and destroy cars, damage trucks, destroy small buildings and break a few trees When skiers are caught by avalanches of this size, probability for severe consequences are very high	May cross flat terrain (well below 30°) over a distance of less than 50 m	Length: 300-1000 m Volume: 10,000 m³
4	Very large Avalanche	May bury and destroy trucks and trains May destroy fairly large buildings and small areas of forest Very large avalanches may occur at danger level 3-Considerable and are typical during periods with danger levels High and Very High	Crosses flat terrain (well below 30°) over a distance of more than 50 m May reach the valley floor	Length: 1-2 km Volume: 100,000 m³
5	Extremely large Avalanche	May devastate the landscape and has catastrophic destructive potential Typical for danger level Very High	Reaches the valley floor Largest known avalanche	Length: > 2 km Volume: > 100,000 m³
