An Evaluation of the Seismic Research Observatories

Abstract

This report concludes a four-year evaluation of the Seismic Research Observatories (SRO) and the Abbreviated SROs (ASRO). Five stations are evaluated: SRO -- Ankara, Turkey, Bogota, Colombia, Grafenburg, Germany, and Shillong, India, and ASRO -- Kongsberg, Norway. Major areas of investigation included the analysis of noise levels, trends, and spectral content, and the estimation of the detection capability of each station with regard to specified geographic regions. Estimates were also made of data quality, station reliability, and mixed-event probability. In addition to the above, long-period noise analyses were extended over a full year for the following previously evaluated stations: SRO -- Chiang Mai, Thailand, and ASRO -- Zongo (LaPaz), Bolivia, Kabul, Afghanistan, and Matsushiro, Japan.
