Figure 5. Model cross sections. (a) The CFM (model 1). (b)–(d) Alternative models (models 2, 4, and 5). Model 3 tests along-strike connectivity of the Raymond–Hollywood faults and is not depicted in cross section here. Cross sections are oriented north–south at universal transverse mercator

. The fault plane areas between 5 and 17 km depth, and 3 and 17 km depth, are depicted in each panel. We restrict the extent of the Elysian Park fault by the location and downdip extension of bounding fault planes. Cross-hatch pattern denotes the downdip extent of the Hollywood and Raymond faults.

from the Hollywood faults (model 3), and lengthening the Lower Elysian Park ramp (model 4). Model 5 incorporates all alternative fault configurations tested in models 2–4. See Figure  2 for location.

et al. (1994) is included with the Los Angeles fault. The vertical component of slip rate for the Los Angeles fault in the past 330 k.y. is <0.09−0.13 mm/ yr ( Ponti et al., 1996 ). Major left slip on the Santa Monica, San Vicente, and Hollywood faults is not included because of uncertainty about

the Hollywood faults (model 3), and lengthening the Lower Elysian Park ramp (model 4). Model 5 incorporates all alternative fault configurations tested in models 2–4. The preferred model that matches best the shape of the Las Cienegas monocline is the model with all three modifications (model 5). See Figure  2

(model 3), and disconnecting the Raymond from the Hollywood faults (model 4). Model 5 incorporates all alternative fault configurations tested in models 2–4. The preferred model that matches best the shape of the Las Cienegas monocline and the Elysian Park anticline is the model with all three
