DESCRIPTION:Shear failure of ice during glacier frontal calving events sha
 res many characteristics of rock-slope failures (RSFs) in high mountain ar
 eas\; Nevertheless\, the investigation of gravity-driven instabilities tha
 t shape rock cliffs and glacier fronts have been dissociated research topi
 cs so far.\nThe dynamic processes shaping the termini of glacier fronts -a
 nd thus directly a major contribution to sea level rise- have attracted th
 e attention of the scientific community. Although recent research has shed
  light on the dynamics of tidewater glaciers\, a full understanding of the
  calving phenomena is still elusive. This epistemic uncertainty may be rel
 ated not only to the highly non-linear dynamics of the calving phenomena\,
  but also to the 2D nature and the limited spatial and temporal resolution
  of the techniques typically used for investigating the rapidly evolving g
 lacier front.\nThrough my two year Marie-Curie H2020 project\, I am progre
 ssively adapting my previous research interests (4D investigation of RSF u
 sing Terrestrial LiDAR and Structure-from-Motion photogrammetry) to the in
 vestigation of glacier front dynamics\, aiming to gain understanding of th
 e processes leading to discrete calving events\, to adapt landslide modell
 ing techniques for investigating glacier response to external forces and t
 o explore the apparent randomness of calving events. Working in the revers
 e direction\, this research project will allow me to analyse a plethora of
  recorded calving events in order to shed light on natural slope evolution
