In this work we present the monitoring of the displacements, on an hourly time scale, of a rock glacier located in Val Senales (European Alps, northern Italy) with a ground based synthetic aperture radar.

We observed velocity fluctuations occurring at a very regular pace, characterized by phases of sharp acceleration (up to 0.9 mm/hr) lasting 4–11 hr followed by long phases of stagnation lasting 13–20 hr. This study describes an unprecedented observation of an hourly velocity rhythm of an active rock glacier and opens up new perspectives in the analysis and interpretation of rock glacier kinematics.
