LONG-PERIOD SEISMOGRAPH DEVELOPMENT

Abstract

Equipment was designed and constructed to perform a thermal noise experiment. The objective of the experiment was to experimentally investigate the spectral distribution of noise energy in seismometers and galvanometers and their interconnections. The equipment used in the experiment is described. A long-period triaxial borehole seismometer was designed. The design has preserved ideal La Coste geometry in that changes in period are accomplished through a controlled positive restoring force rather than through alteration of the geometry. Also, temperature compensation is designed to preserve the geometry. The seismometer is designed such that it will withstand shipping and installation acceleration while completely assembled.
