Abstract

Temporal variations in mountain permafrost creep are discussed within a regional study on rockglacier kinematics. On all investigated active rockglaciers in the Turtmann valley, a distinct acceleration of horizontal velocities has been recorded since the early 1990s. The link between surface velocities and temperature development is investigated at 2 different scales. The signal of rockglacier speed-up in the period 1993-2001 fits well with the general increase in air temperature recorded during the 1990s. On the local scale, the pattern of BTS values coincides well with the surface-velocity pattern, but in areas with high velocities the BTS temperatures are clearly below -3°C
