Abstract :
A new signal processing method for detecting electromagnetic radiation due to the earthquake activities are presented. The radiation is usually contaminated by background noises. In this paper, a simple method which deals with difference data between the latest data and averaged data. over past several years are proposed. The good performance was obtained to detect a precursor signal of an earthquake by utilizing the proposed method.
