The mission of the Southern California Earthquake Data Center (SCEDC) is "to maintain an easily-accessible, well-organized, high-quality, searchable archive of earthquake data for research in seismology and earthquake engineering." This website "provides access to a large and well-maintained Oracle database of earthquake data in a very active seismic region and is able to provide near real-time access to data, approximately 2-3 minutes after an event. The SCEDC currently archives nearly 3000 data channels from 375 stations, processing and archiving an average of 15,000 earthquakes each year."
