ELF Band Electromagnetic Wave Observation of the East Japan Huge Earthquakes
The huge earthquake of M9.0 hit the East North Japan off the Pacific Ocean on March 11, 2011. We have obtained the ELF band (223/233Hz) electromagnetic radiation data of the quakes for ten years. The radiation consists of the sferics reflected from the lower ionosphere of 45-60km height with modulation by the quake’s induced electric field. In this paper, analytical methods for detecting earthquake precursors are discussed.
