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).
