We present the first comprehensive database of active and potentially-active continental fault in Chile based on existing studies and new mapping at 1:25,000 scale using geologic and geomorphic criteria and digital elevation models derived from TanDEM-X and LiDAR data. The database includes 959 fault strands grouped into 17 fault systems and classified based on activity (78 proved, 592 probable, 288 possible). The database is a contribution to world compilation of active faults with applications in seismic hazards, paleoseismology, landscape evolution processes, geothermal exploration, and in the study of potential feedbacks between continental deformation and the plate-boundary seismic cycle along subduction zones.本研究基于已有研究成果，以1:25000比例尺开展新填图工作，采用地质与地貌判别准则，并依托TanDEM-X与激光雷达（LiDAR）数据生成的数字高程模型，构建了智利境内首个覆盖全面的活动与潜在活动大陆断层数据库。该数据库包含959条断层段，归为17个断层系统，并按活动性分级：其中78条为已证实活动断层、592条为大概率活动断层、288条为可能活动断层。本数据库为全球活动断层汇编工作作出了重要贡献，可应用于地震灾害研究、古地震学、地貌演化过程分析、地热勘探，以及俯冲带区域大陆变形与板块边界地震周期间潜在反馈机制的相关研究。
