2004 - Hauksson, Chi and Shearer: locations using double-difference
Relocated catalog from SCSN for 1984 to 2002 that combines both HypoDD and locations determined using 3D velocity models. The recommended use of this catalog is for analyzing spatial and temporal seismicity patterns. The magnitudes available from the SCEDC may be more up to date. Any statistical research should be double checked by using magnitudes from the SCEDC. Relocations done by Egill Hauksson, and released in February 2004 If you use these locations, please reference: Hauksson et al., 2003. |

2005 - Shearer, Hauksson and Lin: locations using waveform cross-correlation and cluster analysis
Event locations in southern California as computed by the source-specific station term, waveform cross-correlation and cluster analysis methods. Please reference: Shearer, P., E. Hauksson and G. Lin, Southern California hypocenter relocation with waveform cross-correlation, Part 2: Results using source-specific station terms and cluster analysis, Bull. Seismol. Soc. Am., 95, 904-915, doi:10.1785/0120040168, 2005. |

2000 - Richards-Dinger and Shearer: locations using source-specific station terms
Locations obtained for 1975, 1976, and 1981-1998, using existing phase picks and the source-specific station term method and a uniform 1-D velocity model. The locations are also described in the paper "Earthquake locations in southern California obtained using source-specific station terms" (J. Geophys. Res., Vol. 105 No. B5, 2000) |

2005 - Hardebeck: focal mechanisms from P-wave polarity and S/P amplitude ratios
An earthquake focal mechanism catalog for southern California earthquakes 1984-2003, determined using a combination of catalog P-wave first motion polarities and S-wave/P-wave amplitude ratios. For now, please reference: Hardebeck, J. L. and P. M. Shearer, Using S/P Amplitude Ratios to Constrain the Focal Mechanisms of Small Earthquakes, Bull. Seismo. Soc. Am., 93, 2434-2444, 2003. |

SCEC Community Velocity Model
The 3D Community Velocity Model provides a unified reference model for the several areas of research that depend of the subsurface velocity structure in their analysis. The velocity models are a Fortran code and associated files that are downloaded, compiled, and run locally. The user queries the models by creating an input file of latitude, longitude, and depth values, and the model returns Vp, Vs, and density at each of those points. Some web based interfaces to handle model queries have been developed and are available from the SCEC Community Modeling Environment. It is recommended to use version 4 over previous versions. |
