DEEP SUBSURFACE GROUND STRUCTURE OF THE SOUTH-WESTERN KANTO DISTRICT
|
´˜^i‰pjF
Investigation of deep ground structure was performed by means of seismic prospecting using explosions in the south-western Kanto district. As the results included some uncertainty because of lacking reverse explosions, other informations from geological studies, gravity surveys and observed seismograms were associated. Through the discussion with these informations, probable deep ground structure was obtained more clearly. The most important discussion in this paper is how to know e true P-wave velocity of the bedrock.
