Answers
here is your answer mate
landslide
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. ... Almost every landslide has multiple causes.
causes of landslide
When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides. Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil. Heavy Rainfall: When sloped areas become completely saturated by heavy rainfall many times landslides can occur.

Answer:
Landslides: Landslide is defined as the movement of a mass of rock, debris, or earth down a slope. ... Earthquake shaking and other factors can also induce landslides underwater. These landslides are called submarine landslides. Submarine landslides sometimes cause tsunamis that damage coastal areas.
Causes of landslides: When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides. Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil. Heavy Rainfall: When sloped areas become completely saturated by heavy rainfall many times landslides can occur.
Protection from landslides: Covering the land with impermeable membranes in order to prevent water infiltration in the landslide; Directing surface water sources away from the landslides; Draining ground water streams away from the landslides; Minimizing irrigation on the surface of the soil.
