Preliminary Evaluation of the UBSO Vertical Array
Abstract
The vertical array at the Uinta Basin Seismological Observatory consists of six short-period seismographs distributed along the 9000-foot depth of the Carter U. S. No. 1 well. A study of four data samples containing teleseismic earthquake signals indicated a maximum improvement of about 9 dB in signal-to-noise ratio of a single vertical array instrument to a surface instrument. Analyses of two noise samples indicate that the noise field consists of fundamental mode Rayleigh waves for periods greater than 2.5 seconds, at shorter periods the noise field is primarily dominated by P-wave noise.
