Answer:

Earthquakes are a major cause of landslides. Landslides occur when masses of rock, earth material, or debris flows move down a slope due to gravity. Landslides can occur on any terrain if the conditions are right, and cause significant damage and casualties to people and property. In this lesson, students learn about earthquake-induced landslides and the associated hazards, and how and why landslides occur. In addition, students discuss steps they can take to reduce landslide hazards.
