Most of these include sites of engineering importance such as dams, bridges, utilities and large buildings. These records represent a comprehensive collection of accelerograph data suitable for the analysis of dynamic structural response and soil-structure interaction. Approximately 4000 records in the database are available from ground response sites. Obtained from a wide variety of geologic environments, these records comprise an important subset useful for the study of seismic attenuation in a wide variety of regional geologic media ranging from young alluvium to hard rock. Several near source records included in the database are useful for source mechanism studies.
Numerous records are available from several diverse arrays.
