The term "debris pile" refers to a collection or accumulation of debris, rubble, or wreckage that has been gathered together in one place. This can include various types of materials such as rocks, soil, wood, metal, concrete, and other man-made objects. Debris piles are often formed after natural disasters like earthquakes, hurricanes, tornadoes, or human-caused events like building demolition, landslides, or avalanches. They can pose risks such as potential hazards to public safety and the environment if they contain contaminants or unstable materials that could cause further damage during storms or other disturbances.
