About the NCEDC
The Northern California Earthquake Data Center (NCEDC) is the permanent archive and distribution center for various types of digital data relating to earthquakes in central and northern California. Time series data come from broadband, short period, and strong motion seismic sensors, GPS, and other geophysical sensors.
The NCEDC is a joint project of the Berkeley Seismological Laboratory (BSL) and the U.S. Geological Survey (USGS) at Menlo Park. The NCEDC also provides support for earthquake processing and archiving activities of the Northern California Seismic System (NCSS), a component of the California Integrated Seismic Network (CISN).
If you use data from the NCEDC, we ask that you acknowledge both the NCEDC and the organizations that contributed the data.
