Continuation of the Seismic Research Observatories Evaluation

Abstract

This report presents the results of an ongoing evaluation of the Seismic Research Observatories performed by Texas Instruments Incorporated at the Seismic Data Analysis Center in Alexandria, Virginia. Seven stations of the types noted are evaluated: SRO: Albuquerque, New Mexico (ANMO), Mashhad, Iran (MAIO), Chiang Mai, Thailand (CHTO); ASRO: Charters Towers, Australia (CTAO), La Paz (Zongo), Bolivia (ZOBO), Kabul, Afghanistan (KAAO), Matsushiro, Japan (MAJO) . The major area of investigation in the evaluation were: Analysis of RMS noise levels, RMS noise trends, and noise spectral content; Estimation of the detection capability of the individual stations on a regionalized basis; Estimation of the discrimination capability of the individual stations; Estimation of the detection capability of the stations functioning as a network; and Evaluation of the performance of the short-period detector. Estimates were also made of data quality, station reliability, and probability of mixed events. Conclusions regarding the above areas of interest and plans for further work are also presented in this report.
