Site response at Treasure Island D. Roy", S.

The site response analysis was performed for Treasure Island, in San Fracisco Bay, using the procedures incorporated in computer programs CHARSOIL (Streeter, et al. [1]), MASH (Martin and Seed [2]) and SHAKE (Schnabel, et al. [3]). The base motion for this site was estimated from the nearby rock-site at Yerba Buena Island as recorded during the 1989 Loma Prieta earthquake. The computed peak horizontal accelerations compared well with the recorded data but the peak spectral accelerations were underestimated. The pore water pressure computation predicted liquefaction for the event. INTRODUCTION During an earthquake,
