Landslide: A landslide is the movement of rock, earth, or debris down a slope due to gravity, often triggered by factors like rainfall, earthquakes, or human activity.

Mass Wasting: Mass wasting refers to the process by which soil and rock move down slope under the influence of gravity, encompassing various forms such as landslides, rockfalls, and mudslides.

Hazard Mitigation: Hazard mitigation involves strategies and actions aimed at reducing the risk of damage from natural disasters, such as improving infrastructure and implementing early warning systems.
