Earthfalls, also known as landslides or mudslides, occur when masses of soil, rocks, and debris suddenly slide down a slope. Synonyms for earthfalls include avalanches, rockslides, and mudflows. Avalanches are particularly dangerous in snowy and mountainous areas, as they can cause widespread damage and even deaths. Rockslides can be caused by earthquakes, heavy rainfall, or erosion, and are common in hilly and mountainous regions. Mudflows are the result of heavy rain and are more common in areas with loose soil and vegetation. Other synonyms for earthfalls include landslips, slope failure, debris flow, and slope collapse. These natural disasters can have devastating effects on communities and infrastructure, making their prevention and mitigation crucial.
