Overview

• Landslides are triggered by natural factors like rainfall, earthquakes, and volcanic activity, as well as human activities such as deforestation and construction.
• Countries like Papua New Guinea, the United States, and Nepal experience frequent landslides, with devastating impacts on communities and infrastructure.
• Effective prevention includes improving drainage, constructing retaining walls, and reforestation, though these measures are not foolproof.
• Accurate prediction of landslides is difficult due to the complex interplay of geological materials and environmental conditions.
• Climate change is expected to increase the frequency of landslides, particularly in mountainous regions.
