Definition: The slow deformation (or time-dependent shear strain) that results from long-term application of a stress too small to produce failure in the frozen material.  NSIDCCryosphere 

The slow deformation (or time-dependent shear strain) that results from long-term application of a stress too small to produce failure in the frozen material  IPAPermafrost 

The slow deformation that results from long-term application of a stress unable to produce failure in the frozen material. In frozen soils, Creep deformations are due mainly to the Creep of Pore Ice and the migration of unfrozen pore water. In ice-saturated frozen soils, most Creep deformations are distortional with little or no volume change. In frozen soils with large unfrozen water contents or in unsaturated frozen soils, slow deformations due to consolidation, and Creep due to volume change, may also occur. Usually, a large portion of the Creep deformation is permanent.  TrombottoGeocryology
