Time forecast of a break-off event from a hanging glacier
A cold hanging glacier located on the south face of the Grandes Jorasses (Mont Blanc, Italy) broke off on the 23 and 29 September 2014 with a total estimated ice volume of 105 000 m 3 . Thanks to accurate surface displacement measurements taken up to the final break-off, this event was successfully...
