3.1 Surface deformation and slip distribution

The predicted permanent surface displacements calculated from the model are shown in Figure 10 and on the map. The model can be used to estimate the displacement, tilt, strain, or stress of any point in the greater Los Angeles region. The predicted surface deformation field is dominated by northeast-southwest contraction and east-west expansion (Figure 10). The Santa Susana Range and the San Fernando Valley were elevated by 10 to over 40 cm. The amount of uplift increased from south to north across the valley and was greatest in the Santa Susana Range where it was up to 50 cm. The vertical deformation decreases to zero within 15 to 20 km of the epicentral area and is almost absent in the Santa Monica Mountains.
