WebOne, wildfires eliminate plants that act to anchor soils, thus promoting mass-wasting events. Two, fire can dry and loosen upper layers of soil, making them more susceptible to movement. Lastly, fires can "bake" the ground, creating a water repellant layer at a shallow depth; this barrier may increase surface runoff and WebMass Wasting is when material falls under influence of gravity with little or no transporting agent. And erosion refers to processes that move material to another site under the influence of transporting agents such as water, ice, and/or wind.

WebHow might a wildfire influence mass movement? Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional force of rain. Mass-wasting events often have a trigger: something changes that causes a landslide to occur at a specific time. It could be rapid snowmelt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, rapid-stream erosion, or human activities, such as grading a new road.

This can result from rapid melting of snow or ice, heavy rain, or some type of event that changes the pattern of water flow on the surface. Rapid melting can be caused by a dramatic increase in temperature (e.g., in spring or early summer) or by a volcanic eruption.
