Scientists and engineers may find useful seismic data among these links for research purposes. The southern California earthquake catalog is currently archived by the SCEC Data Center. The catalog contains earthquakes from 1932 to present recorded by the SCSN only. It is available in two different formats, and a catalog search is available. TriNet seismic waveform data is currently being archived for a subset of the sites only. Data for all sites will be archived in the future. The SCEC Data Center archives the triggered broadband seismic waveform data for TriNet. The strong motion data is currently archived by the individual network partners.
