 Joint inversion shear velocity results
[Berg et al., (2018)] Joint inversion shear velocity (Vsv, km s-1) results for depth of (a) 0.5 km,
(b) 2 km, and© 9 km. Also shown are the differences between final and starting models for
depths of (d) 0.5 km (e) 2 km (f) 9 km. Cross-sections denoted in (e) are shown in the next figure.

Cross-Sections
[Berg et al., (2018)] Cross-Sections (above Figure) of (left) final inversion Vsv results and (right)
difference between final and initial (CVMS) Vsv. (a) A-A’ cross section with the San
Cayetano, San Gabriel, Clearwater, San Andreas, Lockhart and Garlock Fault surface
traces marked. (b) B-B’ cross-sections with the Newport-Inglewood, Whittier, Sierra
Madre and San Andreas fault surface traces marked. (c) C-C’ cross-sections with
Elsinore, San Jacinto, Banning and Mill Creek fault surface traces marked. (d) D-D’
cross-section with Elsinore, San Jacinto and San Andreas fault surface traces marked. (e)
E-E’ cross-section with Elsinore and Superstition Hills faults and Brawley seismic zone
labeled. (f) F-F’ cross-section with San Cayetano and San Andreas faults marked. (g)
G-G’ cross section with Newport-Inglewood, Sierra Madre, San Gabriel, San Andreas,
and Garlock faults marked.
