Next Generation Attenuation Ground Motion (NGA-gm) Project

The University of California has led multiple major research Next Generation Attenuation (NGA) initiatives to develop databases containing ground motion intensity measures, time series, and metadata for shallow crustal earthquakes ( NGA-West3, NGA-West2, NGA-West ), subduction earthquakes ( NGA-Subduction ), and stable continental earthquakes in Central and Eastern North America ( NGA-East ). Furthermore, the NGA projects also provide tools for selecting and scaling ground motion time series to match target hazard. These projects occurred independently, with data resources and interaction tools spread across multiple websites, and with varying levels of functionality.

The NGA-gm database and interaction tools brings the various NGA projects under the same umbrella. The NGA-gm project is made possible by a generous donation from Computers & Structures, Inc. and is hosted at the San Diego Supercomputer Center (SDSC). The project provides users with a one-stop-shop for find ground motion data and metadata, as well as tools to select and interact with the data. A vision for the project is that users will have access to the ground motion data through high performance computing resources at SDSC.
