Landslides occur when masses of rock, mud, or other earth materials move down a slope. This movement can be gradual or it can occur at high speeds. They can be caused by a wide variety of factors, including earthquakes, severe weather, fire, and human activity.
It is important to be informed about changes in conditions in your area that could indicate a landslide is about to occur.
