Strong Motion Records

Earthquake strong motion records/time histories are useful for engineering applications where dynamic analysis is considered. With the introduction of performance-based design specifications in recent seismic codes and regulations, engineers need strong motion records more frequently. This guide:

  • provides information on obtaining copies of strong motion records
  • assists in locating selected data about an earthquake including date, location, time, & site characteristics

Obtaining Strong Motion Records: Accelerograms are available from the organizations, systems, and sites listed below. In some cases, records can be obtained directly via online systems, as well as in a variety of formats, including CD-ROM or hard copy.
