摘要:The acceleration of rock glacier surface velocities over
the two last decades and the destabilization of several
landforms show that permafrost creep conditions
are changing in the Alps. This article summarizes and
presents current understanding of creep behaviour of
rock glaciers in the Swiss Alps and emphasises changes
that have occurred over the last years and decades. The
almost homogeneous interannual behaviour of rock
glaciers despite different geometry and activity rates
indicates a common dependence on external climatic
factors (summer air temperature, seasonal snowcover
development) which govern changes observed in
rock glacier creep rate. The article highlights ongoing
efforts to document interannual variations of rock glacier
kinematics for the whole area of the Swiss Alps.
