The velocity of unstable large ice masses from hanging glaciers increases as a power-law function of time prior to failure.This characteristic acceleration presents a finite-time singularity at the theoretical time of failure and can be used to forecast the time of glacier collapse.However, the non-linearity of the power-law function makes the OMEGA LOTION prediction difficult.The effects of the non-linearity on the predictability of a failure are analyzed using a non-linear regression method.Predictability strongly depends on the time window when the measurements are performed.
Log-periodic oscillations have been observed to be superimposed on the motion of large unstable ice masses.The value of their amplitude, frequency 4 HERB FORMULA DETOXIFICATION and phase are observed to be spatially homogeneous over the whole unstable ice mass.Inclusion of a respective term in the function describing the acceleration of unstable ice masses greatly increases the accuracy of the prediction.
