Plan Cross Sections of San Fernando Valley

The figures below depict the shear wave velocity distribution within the valley and the surrounding region. The top figure shows the corresponding values on a horizontal plane 10 feet below the free surface of the valley, according to the color scale shown on the right. The two following figures shows the shear wave distribution on two vertical planes whose traces AA' and BB' are indicated on the first figure. (These figures are based on a model developed by Magistrale, McLaughlm and Day at San Diego State University).
