earthflow

earthflow
   The mass movement process, associated sediments (earthflow deposit), or resultant landform characterized by slow to rapid flow dominated by downslope movement of soil, rock, and mud (more than 50% of the particles are < 2 mm), and whether saturated or comparatively dry, behaves as a viscous fluid when moving.
   Compare: debris flow (coarser, less fluid), mudflow (finer, more fluid).
