Figure 2. (a) Shear-wave velocity at a depth of 50 m below the model surface (70 m below the Earths surface), for model V12m of the CenCal geologic model. Shoreline is blue. The mapped region corresponds to the red rectangle of Fig. 1. The geographic coordinates of the southwest corner of the region are 121.6763° W longitude, 36.8390° N latitude, 10 km southeast of Watsonville, California. Gray lines correspond to surface traces of major faults. Open circles correspond to subsources on the Calaveras fault for some multisegment source-scenario simulations. Strong-motion stations in Milpitas (MIL) and at San Jose interchange (SJI) are over the Evergreen Basin (EV); San Francisco State University (SFSU) is at the edge of the Merced Basin (MB). Stations G1 and G2 (in the Gilroy Array), CAL (Calaveras Reservoir), CLD (Coyote Lake Dam), and SFO (San Francisco Airport) are also labeled. Other basins are labeled, including San Leandro Basin (SLB). (b) Shear-wave velocity for the V12m rendering of the CenCal geologic model at a depth of 750 m with locations of strong-motion stations (inverted triangles) and sources on two segments of the Calaveras fault, CN (northern) and CC (central) (open circles). The boundary of these segments occurs under the Calaveras reservoir (station CAL). See caption for Figure 2a for additional details.
