1 Introduction
Debris flows are among the most dangerous and destructive natural hazards
that affect human life, buildings, and infrastructures. Starting from the '70s,
significant scientific and engineering advances in the understanding of the pro-
cesses have been achieved [4, 7]. Yet, human expertise is still fundamental for
hazard identification, as many aspects of the whole process are poorly under-
stood; and the acquisition of evidence about the areas under consideration
can only be done vaguely in practice, making it difficult to apply models.
This paper presents a credal network model of debris flow hazard for
