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.
SNOW DIRT 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
27
Qfp, Flood Plain Deposits
29
af, Artificial Fill
