Abstract
A field experiment was conducted over a near-surface cavern with the principal objective of obtaining a spatial definition of the associated Cavity Resonance phenomenon, as reported by Watkins et. al. (1967) and by Godson and Watkins (1968). The results of the experiment were inconsistent with those of the earlier investigators in that all seismic events recorded in the vicinity of the cavity, having vertical velocity components, could be readily identified as standard modes of seismic wave transmission. A persistence of strong horizontal motion was observed for late record times. This horizontal motion was consistently oriented parallel to the cavity boundary, occurred only over an extremely limited range of the traverse at approximately a 25° polar angle to the vertical axis passing through the center of the void, and did not appear to be propagating. This energy might qualify as a cavity resonance phenomenon. © 1975.
