The aim of the study was to map the Potential Release Areas of snow avalanches within Ceahlău Mountain.

1. Mapping avalanche risk using GIS technique in Ceahl ă u Mountain A. Cov ăsnianu , I.R. Grigoraş, L.E. State, S. Hogaş

10. Mapping avalanche risk using GIS technique in Ceahl ă u Mountain Aspect map The South, South-West and South-East versants are the most representative due to the fact that the avalanche risk is higher in those areas.

11. Mapping avalanche risk using GIS technique in Ceahl ă u Mountain Landforms map describes the concavit y/convexity of the terrain. The landform is very useful for snow avalanche risk because it determines the probable snow accumulation areas or the possible areas of propagation . The concave areas are mostly represented by the bed’s rivers. The convex one’s , in general , are represented by the highest slope values.

13. Mapping avalanche risk using GIS technique in Ceahl ă u Mountain The higher probability of producing a snow avalanche is near Toaca Peak and close to Dochia chalet. Avalanche risk classes: 0-5 = low risk (tourism activity not forbidden in winter season) 5-10 = moderate risk (tourism activity permitted only for experienced users) 10-15 = considerable risk (tourism activity admitted under certain conditions) 15-20 = high risk (restricted under certain conditions).

14. Mapping avalanche risk using GIS technique in Ceahl ă u Mountain - The tourist tracks were obtained by GPS technique - Any of those three tourist tracks passes through areas with avalanche risk
