  1. Inversion for a State-Wide CVM

  2. Reference model: SCEC Community Velocity Model 4.0

  3. Ambient-Noise Green’s Functions Dat Syn Ambient noise Green’s function data from Denolleet al., 2009

  4. 0.05 Hz Full-3D Fréchet Kernels for Frequency-Dependent Phase-delay Measurements on Ambient-noise Green’s Functions (Perturbation Kernels for GSDF, Chen et al., GJI, 2010) 0.15 Hz

  5. 2km 10km 20km CVM4 CVM4SI9

  6. Rapid full-3D inversion for CMTs in SC, Lee, et al., 2011, GJI

  7. USGS + Lin perturbation NC3DAW3 2 km 10 km 20 km

  8. BK.BDM (0.02 Hz – 0.04 Hz)

  9. Starting CA3DAW1 Perturbation 2 km 10 km 20 km

  10. To do list • More CA3D iterations, with higher frequencies • Attenuation inversions in SC

  11. ln(Ad/As)

  12. Vp depth 10%

  13. Lin, Li & Clayton 2012, SEG Expanded Abstract 5200 stations (500 were used in the inversion) Shear structure above 300 m depth
