Abstract
In this paper, a new signal processing method appropriate for detecting electromagnetic radiation due to the earthquake activities was proposed. The radiation is usually accompanied by background noises, mainly caused by atmospheric discharges in the tropical regions. A full-band differentiating filter was applied for the received data as a preprocessing. The good performance was obtained to detect a precursor signal of an earthquake by utilizing the proposed method
