STUDY OF SEISMIC SIGNALS AND NOISE DETECTED BY A BURIED ARRAY.

Abstract

Simultaneous recordings of seismic signals and noises with instruments consisting of a short period vertical-movement Benioff seismograph and an array of seven shallowly buried low frequency seismometers were compared. In general, the same earthquake signals were recorded in both systems, but the amplitudes of undesired back ground noise have been reduced in the buried array system. It is concluded that the buried array system produces a cleaner, more outstand ing, P-wave arrival event. (Author)
