The type of natural disaster that involves a rapid flow of water down a slope is called a landslide. Landslides can occur due to heavy rainfall, earthquakes, volcanic activity, or human activities such as deforestation. These events can cause serious damage to infrastructure, homes, and the environment. Fast-moving debris can lead to loss of life and have long-term impacts on landscapes. Monitoring slopes, managing vegetation, and understanding geological conditions are essential for minimizing the risks associated with landslides.
