Abstract
An apparatus for estimating the origin time, the hypocentral distance, and the scale from time-series measured data of the electric field intensity which is observed accompanying a seismic ground motion, comprising a measuring meansfor measuring the electric field intensity, a data storing meansfor collecting and storing measured data from the measuring means, and a data analyzing meansfor analyzing measured data stored in the storing means to detect origin time from the starting time of electric field increase, and to predict the hypocentral distance and the magnitude from the elapsed time from said origin time and said measured data, is provided.
