SCEC Facilities SCEC Data Center The SCEC Data Center at Caltech is the primary archive and distribution center of seismological data recorded by the Southern California Seismic Network (SCSN), and various Portable Seismic Instrument Arrays. The SCEC Data Center made an important step in putting the earthquake catalog, phase data, and seismograms online for the research community, as well as other seismic data such as from the LARSE I and II seismic imaging projects. The SCEC 3-D velocity model is also available from the Data Center. The SCEC Data Center has also incorporated GPS data from GPS campaigns and SCIGN, as well as SAR interferometry data from the WInSAR consortium. UCLA Global Positioning System Center The UCLA Global Positioning System Center group utilitizes geodetic (e.g., levelling, trilateration, triangulation, GPS, and VLBI ) data in the study of crustal deformation. Southern California Integrated GPS Network (SCIGN) Operated by JPL, UC San Diego, USC and USGS under the aegis of SCEC, SCIGN is an array of Global Positioning System (GPS) stations distributed throughout Southern California with emphasis on the greater Los Angeles metropolitan region. Pinon Flat Observatory The Pinon Flat Observatory is operated by UCSD with partial funding from SCEC and is intended to fulfill two roles: (1) to measure, as accurately as possible, crustal deformation in a tectonically active area, and (2) to serve as a testing ground for new geophysical instrumentation. Scripps Orbit and Permanent Array Center (SOPAC) Located at UC San Diego and funded in part by SCEC. SOPAC supports high precision geodetic and geophysical measurements using GPS.    Western North America InSAR (WInSAR) Consortium A collection of universities and public agencies under the aegis of SCEC that was created to manage the acquisition and archiving of spaceborne InSAR data over western North America. Strong Motion Data Center This relational database at UC Santa Barbara provides access to strong ground motion recordings from many countries, agencies and organizations. Empirical Green's Functions Library This relational database at UC Santa Barbara contains over 84,641 seismograms from 1500 Southern California earthquakes. The purpose of this site is to provide fast and easy access to recordings of small earthquakes that might be used as Green's functions for predicting the ground motion from larger earthquakes. Portable Broadband Instrument Facility The Portable Broadband Instrument Center (PBIC) was established by the SCEC at UC Santa Barbara to provide researchers with year-round access to a "pool" of high-resolution, digital seismic recording equipment.
