内容記述 | An analog computer circuit was constructed for the purpose of deducing the original waveform of S-pulse from seismograms. The present paper deals with the six deep-focus earthquakes in the Japan area by use of the records at Matsushiro with mechanical long-period seismographs. It is ascertained that the original pulse-form thus obtained can be well explained by H. Honda's theory of a spherical seismic origin. Good agreement of the theory with the observations enables us to estimate the apparent radius of the origin. If we look for an analytically simple function to approximate the reduced pulse-form, the following expression might be used, V(t)=A・exp(-c2t2),where, A is a function of such factors as earthquake magnitude, hypocentral distance, orientation of nodal planes, and so on. | |||||
