Short summary
The break-off of a cold hanging glacier could be successfully predicted 10 days in advance thanks to very accurate surface displacement measurements taken right up to the final event. This break-off event also confirmed that surface displacements experience a power law acceleration along with superimposed log-periodic oscillations prior to the final rupture. This paper describes the methods used to achieve a satisfactory time forecast in real time.
