These factors include both natural events such as geological weathering and erosion and human-related activities such as deforestation and changes made to the flow of groundwater. Destruction of vegetation by droughts, fires, and logging has been associated with increased risk for landslides.

Explanation:
The primary cause of a landslide is the influence of gravity acting on weakened materials that make up a sloping area of land. While some landslides occur slowly over time (e.g., land movement on the order of a few meters/yards per month), the most destructive ones happen suddenly after a triggering event such as heavy rainfall or an earthquake.
That was the case for the last extremely deadly mudslide in the continental U.S., the 2014 Oso mudslide, which took 43 lives and destroyed 49 homes and other structures. A portion of an unstable hill collapsed, sending mud and debris to the south across the North Fork of the Stillaguamish River, engulfing a rural neighborhood.
