Short summary
Rockfall hazard zoning analyses can be based on qualitative observations. For this reason, expertise is of great importance in determining the hazard. To test this hypothesis, an experiment is proposed to evaluate the importance of subjective assessment: three populations with different level of expertise assessed the level of rockfall hazard on three sites using a qualitative and a quantitative method. A statistical analysis shows that there is a non-significant influence of the level of expertise.
