Mudslide is the most rapid and fluid type of

natural stability of a slope.

The factors that cause mudslide to occur
Nature
Landslides are caused by disturbances in the natural stability
of a slope. They can happen after heavy rains, droughts,
earthquakes or volcanic eruptions. Mudslides develop when
water rapidly collects in the ground and results in a surge of
water-soaked rock, earth and debris.
