Quick Clay - a Reason to Avoid Norwegian Farm Holidays!
The Landslide Blog has come up with two fantastic videos from Norway. THE FIRST is of a recent landslide at Alta in northern Norway. Nothing much happens until 2 minutes 20 seconds in and then be amazed.

The SECOND VIDEO is much older - and it shows - but it gives the scientific explanation of Quick Clay Landslides. About two minutes in they give a vivid illustration of solid clay becoming liquid.
