Seismo-tectonics of the 1923 kanto earthquake

Abstract

Kanto earthquake of 1923 was associated with various sorts of seismic and tectonic effects such as surface displacements, seismic damages, tsunamis and volcanism. The writer previously proposed a fault-origin model of the earthquake from a geodetic viewpoint. The present paper is to develop the geodetic model on the idea that the various sorts of the associated effects in 1923 can be interpreted with a simple fault-origin model, equally well. The geodetic model is slightly revised to fit the effects. Thus it is found out that the fault model can be much simplified except for the area immediately adjacent to the fault. The fault is technically interpreted as one of the transform faults along the northeastern boundary of the Philippine-Sea plate with the Asian plate. © 1974, The Seismological Society of Japan, The Volcanological Society of Japan, The Geodetic Society of Japan.
