An article in today's New York Times discusses the damage associated with "slow" landslides. I think this is just another name for the problem known as slope creep. The article can be found here:http://www.nytimes.com/2011/06/14/nyregion/creeping-landslide-puts-ny-house-on-precipice.html?_r=1&ref=nyregion. The article points out that developers sometimes ignore the problems associated with an "ancient landslide." In other words, the developer has information about soils movement in the past, but chooses to ignore or downplay it in developing the home.
