An acoustic source for infrasonic electromagnetic wave exploration including: an electrically conductive, generally cylindrical tubular member for containing an electrically conductive fluid, the tubular member having a closed top end, an open bottom end, an interior wall and an internal diameter; an electrode axially positioned within the tubular member, wherein the electrode is axially positioned within the tubular member at a distance equivalent to about three times the internal diameter of the tubular member to enable the acoustic source to produce high energy acoustic waves having a substantial portion of acoustic wave energy in the infrasonic frequency range; means for electrically connecting the electrode to the negative electrical pole of an external source of DC electric power; and means for electrically connecting the tubular member to one of: a positive electrical pole of the external source of DC electric power; an electrical ground; and a combination of the above.
