A new model which consists from three dimensional distribution of seismically active regions and the attenuation curve that takes focal depths into account for predicting peak ground accelerations (PGAs) is proposed, in order to make microzoning the central Kanto area and estimate a more rational and practical design ground motion level for ordinary structures on practical design base layer. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
