Landslides In China, California, India... (part 2): Biggest Landslide Caught on Camera

  • 🎬 Video
  • ℹ️ Description
landslide has at one time or another been used to cover almost all forms of mass movement of rocks and regolith at the Earth's surface. In 1978, in a very highly cited publication, David Varnes noted this imprecise usage and proposed a new, much tighter scheme for the classification of mass movements and subsidence processes. This scheme was later modified by Cruden and Varnes in 1996, and influentially refined by Hutchinson (1988) and Hungr et al. (2001). This scheme results in the following classification for mass movements in general, where bold font indicates the landslide categories:

landslides are restricted to "the movement... of shear strain and displacement along one or several surfaces that are visible or may reasonably be inferred, or within a relatively narrow zone", i.e., the movement is localised to a single failure plane within the subsurface. He noted landslides can occur catastrophically, or that movement on the surface can be gradual and progressive. Falls (isolated blocks in free-fall), topples (material coming away by rotation from a vertical face), spreads (a form of subsidence), flows (fluidised material in motion), and creep (slow, distributed movement in the subsurface) are all explicitly excluded from the term landslide.

Under the scheme, landslides are sub-classified by the material that moves, and by the form of the plane or planes on which movement happens. The planes may be broadly parallel to the surface ("translational slides") or spoon-shaped ("rotational slides"). Material may be rock or regolith (loose material at the surface), with regolith subdivided into debris (coarse grains) and earth (fine grains).

Nevertheless, in broader usage, many of the categories that Varnes excluded are recognised as landslide types, as seen below. This leads to ambiguity in usage of the term.

These are either some of the bravest people I have ever seen or the dumbest. Cannot really say which. " I m just waiting to see if one big rock will hit me".

I’m amazed that someone just happens to be filming at time of collapse. Or are some of the slides expected over a period of time ? It looks like some of the slides are continuation of previous slide.
