The writer determined fault parameters of the great Kanto earthquake of 1923 on the basis of the geodetic data by triangulation and levelling. Thus he attempted to establish a dislocation model which reasonably explains all the available data on the surface displacements associated with this earthquake. Basically the fault line is assumed to extend from the Kozu area southeastward with its strike N45°W, parallel to the trend of the Sagami trough. The shape of the fault plane is assumed to be a rectangular plane. The fault models which was finally accepted is as follows. total length: 130km, width: 65km, dip. 45° and a fault displacement : 6 m (right lateral strike slip) and 3 m (reverse dip slip). Generally speaking, this earthquake seems to indicate a differential movements of the two crustal plates bounded by the Sagami trough. The fault's dimension, geometry and direction of the slip are all in good harmony with the seismological evidence on wave radiation.|1923年の関東大地震の震源パラノーターを地殻変動を使つて推定した.
