尽管认识、预测、缓解措施和预警系统有所改进，但西半球山体滑坡造成的经济损失和人员伤亡似乎仍在增加，因为人口压力导致山体滑坡易发地区的开发不断增加。本文指出了美洲社会经济损失的突出例子。山体滑坡影响自然环境的以下要素：(1) 地球地下和海底表面的地形/形态，(2) 河流、溪流、森林和草原，以及 (3) 地球表面及其溪流和海洋中本地动物的栖息地。环境扰动是地球表面因重力质量消耗和侵蚀而退化的总体趋势的结果。
In spite of improvements in recognition, prediction, mitigative measures, and warning systems, economic losses and casualties due to landslides in the Western Hemisphere appear to be growing as a result of increasing development of landslide-prone areas due to population pressures. This paper notes outstanding examples of socioeconomic losses in the Americas. Landslides impact the following elements of the natural environment: (1) the topography/morphology of both the subaerial and submarine surfaces of the Earth, (2) rivers, streams, forests, and grasslands, and (3) habitats of native fauna, both on the Earth's surface and in its streams and oceans. Environmental disturbances are results of general tendency toward degradation of the Earth's surface by gravitational mass wasting and erosion.
