Project Abstract
 The primary objective of the Southern California Earthquake Data Center is to archive seismic data recorded by the Southern California Seismic Network and make it available and searchable for the scientific community in near real-time. In 2012 we added 61,570,083 hours of continuous seismic data for 436 stations and parametric and waveform data for 16,565 local events and 479 teleseismic earthquakes. The SCEDC continues to improve distribution of its products by developing web services for data access. We also began archiving new data types that are of interest to the earthquake research community such as real time GPS displacement waveforms, and class C data.
Intellectual Merit The Data Center is a central resource of SCEC and continues to be an integral part of the Center. In 2012, the SCEDC continued to contribute to the SCEC scientific community by providing online access to a stable and permanent archive of seismic waveforms and earthquake parametric data. The seismological data archive held at the SCEDC has contributed significantly to the publication of many scientific papers pertinent to the region, most of which have SCEC publication numbers. The Caltech/USGS catalog archived by the SCEDC is the most complete archive of seismic data for any region in the United States.
Broader Impacts The SCEDC has allowed the data to be distributed to a much broader community of scientists, engineers, technologists, and educators than was previously feasible. The electronic distribution of data allows researchers in the world-wide scientific community to analyze the seismic data collected and archived in southern California and contribute their results to the SCEC community.
