Development of the Model 52500 Strain-Inertial Seismometer System (Prototype)

Abstract

Two prototype strain-inertial seismometer systems were designed and built to investigate the use of linear combinations of collocated strain and inertial data for providing enhanced seismic signal-to-noise ratios. These instruments have undergone initial laboratory testing and preliminary field evaluation. The preliminary evaluation data indicate: (1) An improved signal-to- noise ratio can be achieved by using linear combinations of the strain and inertial data, the major improvement occurring in the frequency range of the cultural microseisms (3 to 5 Hz). (2) A reduction in the instrument noise level of the strain output of the seismometer will be required prior to final evaluation.
