Archive of an Earthquake Ground Motion Relational Database (GMDB) for Engineering Applications

This dataset provides static archives of public releases from the Earthquake Ground Motion Relational Database (GMDB) for Engineering Applications (https://gmdatabase.org/). The GMDB is an ever evolving repository for uniformly-processed ground motion data, associated metadata, and intensity metrics (e.g., peak metrics, cumulative absolute velocity, Arias intensity, pseudo-spectral acceleration, effective amplitude spectra). Data stored within the GMDB includes the unification of published datasets (e.g., NGA-West2, NGA-East, and Hellenic Strong Motion Database) and ongoing data collection efforts which involve one or more project team members. Releases of individual versions include resources related to the relational structure (i.e., schema), data presented in individual tables as they are stored within the GMDB, and pre-compiled flatfiles formatted for user-convenience. Using these resources, users are able to construct a replica of a particular GMDB version in a local environment. Versioned data are also available on the GMDB web interface and application programming interface (API). The GMDB is anticipated to evolve with the addition of new data and corrections/updates to existing metadata associated with individual ground motions. This repository will be updated periodically as subsequent versions of the GMDB are released to the public. For detailed information related to the GMDB, please refer to Buckreis et al. (202X) “A global application programming interface (API)-enabled earthquake ground motion relational database (GMDB) for engineering applications”, Earthquake Spectra (in review).

本数据集提供了面向工程应用的地震动关系数据库（Earthquake Ground Motion Relational Database，GMDB）官方公开版本的静态归档文件，其官方网址为https://gmdatabase.org/。GMDB是一个持续迭代更新的存储库，收纳经过统一处理的地震动数据、关联元数据以及强度指标（如峰值指标、累积绝对速度、阿里亚斯强度、拟谱加速度、有效振幅谱）。GMDB中存储的数据整合了已公开的数据集（如NGA-West2、NGA-East以及希腊强震数据库），同时纳入了由一个或多个项目团队参与的持续数据采集工作。各公开版本的发布资源包含数据库关系结构（即模式（schema））相关文件、GMDB内部存储的单表数据，以及为方便用户使用预编译的平面文件。借助上述资源，用户可在本地环境中搭建特定GMDB版本的复刻副本。GMDB的网页界面与应用程序编程接口（Application Programming Interface，API）也提供带版本号的数据集访问服务。GMDB将持续迭代更新，包括新增地震动数据，以及对单条地震动关联的现有元数据进行修正与更新。随着GMDB后续版本面向公众发布，本归档库也将定期更新。如需了解GMDB的详细信息，请参阅Buckreis等人（202X年）发表于《地震谱》（Earthquake Spectra，待刊）的论文《面向工程应用的支持全球应用程序编程接口（API）的地震动关系数据库（GMDB）》。
