Landslide, mudslide, debris flowit doesn't matter what you call it, the outcome is the same: normally stable and stationary soil gets a bad case of wanderlust.

This can occur almost anywhere, but Central Americawith its precipitous hills, frequent heavy rainstorms and unstable volcanic soilis probably the number one hotspot.
