Study of the Feasibility of Long-Range Seismic Communications
Abstract
The fact that seismic energy from earthquakes and large explosions can be readily detected by seismic stations all over the world suggests the possibility of using seismic waves for worldwide communications. Although it is clear that seismic communications will be restricted to a narrow bandwidth and will propagate at relatively low velocities, such a system may nevertheless have some unique advantages. This study is undertaken in order to explore the characteristics and potential applications of seismic communications and to determine whether further studies are warranted. The fact that such a communication link would be virtually indestructible (enabling it to serve as a hardened, emergency backup for a limited vocabulary of critical messages) makes an evaluation of the feasibility of seismic communication worthwhile. A brief comparison of the characteristics of possible techniques for achieving a hardened backup communication system will help delineate the potential value of a seismic system.
