landslide Scientific  
/ lăndslīd′ /
  1. The rapid downward sliding of a mass of earth and rock. Landslides usually move over a confined area. Many kinds of events can trigger a landslide, such as the oversteepening of slopes by erosion associated with rivers, glaciers, or ocean waves; heavy snowmelt which saturates soil and rock; or earthquakes that lead to the failure of weak slopes.

  2. The mass of soil and rock that moves in this way.


Etymology

Origin of landslide

An Americanism dating back to 1830–40; land + slide

Explanation

When dirt and rock from a mountainside are sliding down, call it a landslide. Another kind of landslide takes place when one candidate soundly defeats another in an election. With either type of landslide, it's probably safest to stay out of the way! The political meaning of landslide is commonly used, but it's not the word's original definition. A geographical landslide occurs when a huge amount of earth slides down a slope or mountain, usually displacing rocks and vegetation and often houses and buildings as well. Landslides are caused by erosion, heavy rain, and earthquakes, among other events, and they're disruptive enough to give rise to the figurative meaning.
