ABSTRACT:
A seismic generator for communicating from either above or below the surface of the earth is disclosed. The generator includes a system of eccentrically weighted masses such as, for example, unbalanced flywheels, which can be rotated to produce a seismic signal capable of being detected at great distances either on the surface or underground.
