Abstract:

Near-field strong-motion accelerograms of the San Fernando earthquake and three of its aftershocks recorded at Pacoima Dam were analyzed using Haskells moving dislocation model. For the main shock, it was found that 1 The effect of stick-slip segmented rupture velocities is not prominent within a moderate range of rupture velocities 2 A hinged fault surface can produce the necessary initial negative polarity of the vertical velocity trace 3 Using Jungles and Fraziers 1973 solution, the Haskell model produces very large amplitudes compared to those observed.
