Many of the landslide videos that I have featured on here have been quite low quality. The one featured below is unusually good. I have updated this to provide the (better) Youtube version:
The slide apparently occurred at Polk County in Tennessee, USA, on 10th November 2009. The slide appears to be a rockslide on a discontinuity dipping parallel to the slope. An interesting element of this is the clear signs of precursory activity - note the blocks on the road and the small slide that happens just before the main slide.
