抽象的。地震是中亚国家潜在生命损失和经济破坏的最高风险。断层位置和行为的知识在计算和绘制地震危险性图中是必不可少的。以前的努力在编译断层信息中亚产生了大量的数据，发表在有限访问的期刊上，没有公开的数字地图，或在其重要的断层参数，如滑动率的描述有限。这项研究建立在以前的工作，通过改进访问故障信息，通过基于网络的交互式地图和在线数据库的搜索功能，允许用户组织数据的不同领域。本汇编中提供的数据包括断层位置，其地理，地震和结构特征，简短描述，叙述性评论和同行评审出版物的参考。交互式地图在晕映地形地图上显示1196个断层痕迹和34000个地震位置。该在线数据库包含文献中提到的123个断层的属性，分别报告了38个和26个断层的第四纪和大地滑动速率，以及39个断层的地震历史。所有数据均可通过http://www.geo.uni-tuebingen.de/faults/查看和下载。这项工作对中亚地区的地震危险性研究具有影响，因为它总结了重要的断层参数，并可以通过加强公众获取信息来降低地震风险。它还使科学家和危害评估小组能够查明存在数据缺口和需要今后进行调查的结构和区域。
Abstract. Earthquakes represent the highest risk in terms of potential loss of lives and economic damage for central Asian countries. Knowledge of fault location and behavior is essential in calculating and mapping seismic hazard. Previous efforts in compiling fault information for central Asia have generated a large amount of data that are published in limited-access journals with no digital maps publicly available, or are limited in their description of important fault parameters such as slip rates. This study builds on previous work by improving access to fault information through a web-based interactive map and an online database with search capabilities that allow users to organize data by different fields. The data presented in this compilation include fault location, its geographic, seismic, and structural characteristics, short descriptions, narrative comments, and references to peer-reviewed publications. The interactive map displays 1196 fault traces and 34 000 earthquake locations on a shaded-relief map. The online database contains attributes for 123 faults mentioned in the literature, with Quaternary and geodetic slip rates reported for 38 and 26 faults respectively, and earthquake history reported for 39 faults. All data are accessible for viewing and download via http://www.geo.uni-tuebingen.de/faults/ . This work has implications for seismic hazard studies in central Asia as it summarizes important fault parameters, and can reduce earthquake risk by enhancing public access to information. It also allows scientists and hazard assessment teams to identify structures and regions where data gaps exist and future investigations are needed.
