ResumoWe present contours of the largest horizontal and vertical recorded peak velocities of strong ground motion during the Northridge, California, earthquake. Above the fault, the horizontal peak velocities exceeded 100 cm/s. The vertical velocities were larger than 20 cm/s. We also present contours of peak horizontal and vertical strain factors. Through most of the San Fernando Valley and the Santa Susana Mountains, the horizontal surface strain factor was larger than 10−3. The largest horizontal strain factor computed was for the Rinaldi Receiving Station ∼10−2·2. The corresponding vertical strains were >10−3·25 and 10−13, respectively. Through most of the Los Angeles Basin the horizontal peak surface strain factors were between 10−3·75 and 10−3.
