Landslides are a natural hazard that presents a major threat to human life and infrastructure. Although they are a very common phenomenon in Colombia, there is a lack of analysis that entails national and comprehensive spatial, temporal, and socioeconomic evaluations of such events based on historical records. This study provides a detailed assessment of the spatial and temporal patterns and the socioeconomic impacts associated with landslides that occurred in the country between 1900 and 2018. Two national landslide databases were consulted and this information was complemented by local and regional landslide catalogues. A total of 30,730 landslides were recorded in the 118-year period. Rainfall is the most common trigger of landslides, responsible for 92 per cent of those registered, but most fatalities (68 per cent) are due to landslides caused by volcanic activity and earthquakes. An 'fN curve' revealed a very high frequency of small and moderate fatal landslides in the time frame.
滑坡是一种对人类生命和基础设施构成重大威胁的自然灾害。尽管滑坡在哥伦比亚非常常见，但缺乏基于历史记录的对这些事件进行国家范围的全面空间、时间和社会经济评估的分析。本研究详细评估了 1900 年至 2018 年期间该国发生的滑坡的时空模式和社会经济影响。查阅了两个国家的滑坡数据库，并通过地方和区域滑坡目录补充了这些信息。在 118 年的时间内共记录了 30730 次滑坡。降雨是滑坡最常见的触发因素，占已登记滑坡的 92%，但造成的大多数死亡（68%）是由火山活动和地震引起的滑坡造成的。“fN 曲线”显示，在该时间段内，小型和中型致命滑坡的发生频率非常高。
