Diploma thesis Christian Björk
Danger level 3 - considerable
English: considerable > level 3German: erheblich > Stufe 3
The terms „considerable“ and „erheblich“ are not really intuitive and hard to interpret, especially for beginners
Also signify by different feedbacks to the Swiss avalanche warning service as well as in the press
Open questions...discussion
Are there similar difficulties in other languages or for other danger levels?
Is there a need to attend this problem in the working group?
