Abstract :
Our goal is to locate anomalous electromagnetic (EM) source caused by seismic activity for earthquake prediction. For the purpose, we have been measured EM wave of 223 Hz at 35 sites in Japan. This paper analyses relation between EM power attenuation and distance from its source. The relation is necessary to estimate the source location.
