Abstract:

This report presents the results of a continued evaluation of the Seismic Research Observatory stations performed by Texas Instruments Incorporated at the Seismic Data Analysis Center in Alexandria, Virginia. During the time period this evaluation was carried out, data were available from six stations-Albuquerque, New Mexico ANMO Guam, Marianas Islands GUMO Mashhad, Iran MAIO Narrogin, Western Australia NWAO Taipei, Taiwan TATO and Wellington South Karori, New Zealand SNZO. The major areas of investigation in the evaluation were 1 Analysis of RMS noise levels, RMS noise trends, and noise spectral content 2 Estimation of the quality of performance of the short-period automatic event detector 3 Estimation of the detection capability of the individual stations on a regionalized basis 4 Estimation of the discrimination capability of the individual stations and, 5 Estimation of the detection capability of the stations functioning as a network. In the course of processing and analyzing data for these areas of investigation, estimates were made of the data quality, station reliability, and probability of mixed events.
