Database of active and potentially-active continental faults in Chile at 1:25,000 scale

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. Data is provided in ESRI shapefile, Google Earth kmz, and as Excel spreadsheet.

本报告首次全面展示了基于现有研究及新绘制的1:25,000比例尺地质及地貌标准与基于TanDEM-X及LiDAR数据构建的数字高程模型所得到的智利活跃及潜在活跃的大陆断裂数据库。该数据库包括959条断裂带，划分为17个断裂系统，并根据活动性进行分类（已证实78条，可能592条，可能288条）。该数据库是对全球活跃断裂数据汇编的重要贡献，其在地震灾害、古地震学、景观演化过程、地热勘探以及研究大陆变形与板块边界地震周期潜在反馈等方面具有广泛应用。数据提供格式包括ESRI形状文件、Google Earth kmz格式以及Excel电子表格。
