After graduating from the Department of Physics, Tokyo Imperial University in 1917, he was the director of the Earthquake Research Institute. He studied such as consideration of the magma intrusion theory regarding the cause of earthquakes and the proposal of a push-cone shape regarding the

P-wave A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any ...
