Popis:	Extremely Low Frequency (ELF) and Ultra Low Frequency (ULF) band observation of ElectroMagnetic wave (EM) precursor of earthquakes and volcanic eruption has been studied. Three-axial ELF (223 and 17 Hz) high sensitive equipment of order of sub-pico Tesla per root Hertz have detected many precursors of earthquakes and volcanic eruptions for these twenty years. The ULF band system has detected Schumann resonance variation in level and frequency. In this paper, EM precursors of large-scale earthquakes of order Magnitude 7, of recent Offshore Kii-Peninsula Magnitude 6.9 and Magnitude 7.4, and the disaster quakes of Niigata-Chuetu Magnitude 6.8 experienced on 2004 in Japan are discussed. 資料番号: AA0048095042
