Other forms: landslides
A landslide is a mass of earth sliding suddenly down a slope. A landslide blocked the road, cause a landslide, landslide risk.
Water is usually the trigger: heavy rain adds weight and lubricates the failure surface, which is why landslides follow storms. Cutting a slope for a road or a house removes the support at the bottom and is the other common cause. Figuratively a landslide is an overwhelming election win — a landslide victory — which is much the commoner use in the news.
