ABSTRACT:
A human-portable geophysical energy source is disclosed having an earth-coupling element, a means for providing seismic energy operably connected to that earth-coupling element, a lower container and an upper container connected to the means for providing seismic energy, a framework that minimizes vibrations of the liquid by keeping the upper and lower containers inflexible when they are completely filled with liquid, and a hydraulic pump for filling and removing liquid from the containers. The lower container is located spatially between the earth-coupling element and the means for providing seismic energy. The upper container is located spatially above the means for providing seismic energy. The liquid provides mass to impart energy through the earth-coupling element and to maintain coupling with the earth.
