MULTICOMPONENT STRAIN SEISMOGRAPH
Abstract
Work was directed toward five main objectives. They were: (a) To obtain equal phase and amplitude response on the vertical strain and vertical inertial seismograph to measure phase, coherence, and spectra of the seismic noise at WMSO; (b) To evaluate P-wave enhancement by cancelling microseisms using vertical strain and vertical inertial seismographs, and by utilizing the directional properties of the horizontal strain array; (c) To verify a possible 6 dB loss of signal in the vertical strain seismometer; (d) To start a retrofit of strain instrumentation and strain facilities at WMSO; (e) To set up the data channels required for digital recording by Texas Instruments, Inc.
