3. Lithologic Units
Saucedo, G.J., 2005

5. Qb, Beach deposits 4 lines with consistent Vs30 values
Good energy dispersion in Data collected

6. Vs30 vs. Lithology NEHRP Site Class B NEHRP Site Class C
NEHRP Site Class D
NEHRP Site Class E

8. Kelg- Granodiorite

9. Q- Alluvium

10. Qb- Beach

12. Qfp- Flood plain

15. Results
Changed the unit at Lake Tahoe Boulevard and Rainier Rd to Kelp after finding a Vs30 of 1150 m/s
Lowest Vs30 on Pleistocene till deposits.
Highest Vs30 on granodiorite
Most on site class C/D boundary
Artificial fill has Vs30 values comparable or better than Qta, Qfp, Qb and Q

Immediate jump to bedrock velocities an attempt to better match picks.
All lines on Echo Lake Granodiorite have high RMS error values.

25. Q, Quaternary Alluvium 1 Line, PB 1
2nd Highest velocity after Granodiorite
Much better model than granodiorite
