Project Abstract
 Currently the SCEDC archives continuous data from 15595 data channels recorded at 555 SCSN stations, and triggered data from 643 stations. On a 5 year average, the SCEDC archives data from 30,000 earthquakes each year. SCSN/SCEDC operations generate products such as event catalogs, waveform archives, moment tensor solutions, ShakeMaps, and Recent Earthquake Maps. These products are vital to emergency response and earthquake research. Advances in information technology and earth science research have produced intriguing possibilities for the future of seismic data archival. With the advent of DAS data, the seismological research community is able to view a new spatial scale of data. Cloud computing will change how computational resources are managed and give scientists more tools to analyze larger volumes of data.
The Southern California Earthquake Data Center is leading efforts in exploring how these developments can further its core mission of archival and distribution of seismic data and products for earthquake research.
Intellectual Merit The Data Center is a central resource of SCEC and continues to be an integral part of the Center. The SCEDC continues 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 efforts at the SCEDC further SCEC science priorities by improving archive access, archive completeness, and new data products for SCEC researchers. 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.
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.
