Why the fence is slowly tipping over?

Precipitation and Flooding The longer it rains, the deeper the water gets, making the ground mushy and pliable. After a certain point, forces that your fence would usually resist (e.g., wind) can cause the fence to teeter. Your fence posts will tip over, as the muddy earth no longer stabilizes them.

What are the 4 types of landslides?

Landslides are part of a more general erosion or surficial pro- cess known as mass wasting, which is simply the downslope movement of earth or surface materials due to gravity. They are classified into four main types: fall and toppling, slides (rotational and translational), flows and creep.

Where do landslides happen the most?

The primary regions of landslide occurrence and potential are the coastal and mountainous areas of California, Oregon, and Washington, the States comprising the intermountain west, and the mountainous and hilly regions of the Eastern United States. Alaska and Hawaii also experience all types of landslides.

What causes landslide?

Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
