| 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. |

| 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. |
