Abstract

A set of piezometers were embedded in sand deposits on a reclaimed island in Tokyo Bay and a seismograph was placed on the ground surface nearby in order to monitor insitu pore water pressures simultaneously with the horizontal accelerations during earthquakes. During the September 25, 1980 earthquake, the instruments registered increases of pore water pressures corresponding to 19% and 16 % of the effective confining pressure at depths of 6.0 m and 14.0 m, respectively. At the same time, a maximum horizontal acceleration of 95 gal was registered at the ground surface.
