Landslides may occur after a heavy rain or an earthquake or volcanic eruption, causing a mass of earth to suddenly slide away from its location with whatever was on the land with it, be it a house, farm, road or other. It will take out any houses and possibly roads as well.
People have died from landslides and it is important to know the risks in your area for them, and to prepare accordingly. Landslides differ from mudslides in that they are generally slow moving, where a mudslide can be defined as a debris flow.
For those of you who desire to construct a house, have an expert determine if the land is sound before building. They will determine the type of soil and geological integrity of the area and let you know if its risky or not to build there.
If you are in a car and notice damage that has been done due to a landslide, do not take risks because the rest of the road may give way under the weight of your car.

Thousands of landslides occur every year in Canada, but most are small. They occur in all regions but are most damaging in the mountainous regions of British Columbia and Alberta and in the St. Lawrence Lowlands of Quebec and Ontario. Large landslides are less common, occurring only about once every 10 years in Canada.
Landslide risk can be minimized by various methods, including:
- improving drainage
- reducing the angle of the slope
- excavating to unload the top of the slope
- building a protective berm or wall to buttress the bottom of the slope
Containment or diversion structures
- catchment dams and containment basins to control debris and water
- artificial channels or chutes to redirect debris flow
- nets and artificial walls to prevent falling rock or earth from hitting roads or structures
