 note = {P(論文), The illumination phenomena as precursor of earthquakes have not been observed enough as numerical data until now. This report is treated as research to investigate observed illumination phenomena as precursor of earthquakes. An important low during the precursor has been discovered in the co-relation of the energy of the electromagnetic wave and the illuminated time. And the observed method regarding the illuminated visible light is discussed.},
