  abstract = {{T}he {L}aurichard active rock glacier is the permafrost-related landform with the longest record of monitoring in {F}rance, including an annual geodetic survey, repeated geoelectrical campaigns from 1979 onwards and continuous recording of ground temperature since 2003. {T}hese data were used to examine changes in creep rates and internal structure from 1986 to 2006. {T}he control that climatic variables exert on rock glacier kinematics was investigated over three time scales. {B}etween the 1980s and the early 2000s, the main observed changes were a general increase in surface velocity and a decrease in internal resistivity. {A}t a multi-year scale, the high correlation between surface movement and snow thickness in the preceding {D}ecember appears to confirm the importance of snow cover conditions in early winter through their influence oil the ground thermal regime. {A} comparison of surface velocities, regional climatic datasets and ground sub-surface temperatures over six years suggests a strong relation between rock glacier deformation and ground temperature, as well as a role for liquid water due to melt of thick snow cover. {F}inally, {U}nusual surface lowering that accompanied peak velocities in 2004 may be due to a general thaw of the top of the permafrost, probably caused both by two successive snowy winters and by high energy inputs during the warm summer of 2003.},
