New Data
Previous Data
 New database is about three times
larger than PEER’s previous ground
motion set
Database Includes Comprehensive Meta Data
Numerous parameters describing
source/path/site conditions for each
recording:
 Various types of distance measures
 Measured or estimated values of
VS30 for most of recording sites
 Hanging Wall/Footwall classification
Database is Fully Available to the Public
 All time series and
response spectra can
be downloaded from
