The present dissertation describes a rockfall that has affected the Rochers de Valabres slope and discusses one possible mechanism for its occurrence, along with the potential for future ones. ln the absence of an obvious explanatory trigger factor, we set out to examine whether natural daily surface temperature changes could have played a role in this event. ln particular, it is suspected that these slight, yet repeated, perturbations may be a preparatory factor for rockfalls, with a day-to-day cumulative effect. A numerical model strengthens this hypothesis by showing that thermally-induced deformations can be sufficient to cause the graduai downward creep of rock blocks located in an awkward position. To investigate this notion more thor...
