Welcome to the PEER Ground Motion Database

For Shallow Crustal Earthquakes in Active Tectonic Regimes

User Manual Updated Nov 8, 2011 here

The Pacific Earthquake Engineering Research Center (PEER) ground motion database includes a very large set of ground motions recorded in worldwide shallow crustal earthquakes in active tectonic regimes. The database has one of the most comprehensive sets of meta-data, including different distance measure, various site characterizations, earthquake source data, etc. The current version of the database is similar to the NGA (Next Generation Attenuation) database, which was used to develop the 2008 NGA ground motion prediction equations.

The Beta version of the web-based PEER ground motion database provides tools for searching, selecting and downloading ground motion data. The database and web-site are periodically updated and expanded. Comments on the features of this web site are gratefully welcome; please send emails to: peer_center@berkeley.edu

The PEER strong-motion database and the associated flatfiles are still under review, and the documentation is still being developed. They represent a work in progress that is subject to future revisions as a result of the review process and as new information is obtained, or revised interpretations made. They are released in their current version to obtain feedback and comments from the earthquake engineering, seismology, and geology communities worldwide.

The PEER Center, University of California, Berkeley, funding and sponsoring agencies for the PEER ground motion project, and all organizations and individuals who contributed to the compilation, processing, and review of the database and flatfile are not responsible for any inaccuracy or incompleteness of the data, records, and parameters.
