Ground-Motion Relational Database (GMDB)

The Ground-Motion Relational Database (GMDB) has been developed for researchers/engineers to access global ground-motion data and related metadata. The processed time series data, associated metadata, and ground motion intensity measures are organized into a web-served relational database consisting of 32 tables connected by primary/foreign key pairs. Ground motion metadata and intensity measures (but not time series) from the NGA-East and NGA-West2 projects are also contained in the database.
