The Mam Tor creeping landslide

The Mam Tor creeping landslide has been active
throughout the 3600 years since its formation. The
landslide is divided into three main sections; an upper
extensional regime at the head, a central strike-slip
regime, and a lower compressional (in the downslope
direction) regime in the toe. This movement picture
within the slide has been revealed through annual surveys
over a 19-year period. Maximum local displacement rates
in excess of 50 cm/yr have been measured. Local faulting
within the slide, driven by the heterogeneous distribution
of displacements within the main body of the slip gives
rise to a hummocky, irregular topography across the
whole slipped mass. Year-on-year movements prevent a
normal dendritic drainage system from developing, and
local streams drain into isolated ponds with no natural
outlet. Discrete periods of movement, as identified from
high resolution monitoring using underground creep
meters, are typically initiated by high rainfall over a
period of 3–4 weeks before creep can begin, but movements
are normally suppressed in the summer months as a
result of evapotranspiration by vegetation cover, returning
one-third of rainfall to the atmosphere. The Mam Tor
slide is the only active one of five of similar dimensions in
the vicinity.
