Broad band seismic data analysis, September 1984-September 1986

This report contains a detailed description of the SRNY station including its response function, description of the techniques and software used to analyze the data, and evaluations of both the station and processing methods. The station was evaluated through noise studies under both quiet and noisy conditions; its detection and location thresholds; and the frequency, duration, and causes of data loss. The report has been divided into three main sections. The first section gives a description of the broad band digital seismic station SRNY installed near the Rondout Associates, Incorporated (RAI) offices in Stone Ridge, NY. Included in the discussion are the system response functions and an analysis of the causes of data loss. The second section gives details of the data analysis methods used in studying broad band and array data. Although several methods have been studied, much of this section is devoted to the adaptive polarization methods which has shown promise as a single station location tool. The final section examines the noise characteristics at SRNY during both quiet and noisy conditions and compares these levels to the Regional Seismic Test Network Station RSNY in the Adirondack Mountain Region of northern New York. The detection and location capabilitiesmore » of SRNY are also described and single-station locations at SRNY, as well as RSNY, are compared to network locations.« less
