An Interactive System for Long-Period Seismic Processing. Technical Report No. 11. VELA Network Evaluation and Automatic Processing Research

Abstract

The report describes an interactive graphics processing system developed for the PDP-15 computer at the Seismic Data Analysis Center. The system is designed to process long-period seismic data and includes options for interactive bandpass filtering, matched filtering, spectral analysis and parameter measurements. The main intention of the program development has been to investigate the feasibility of using interactive graphics for event detection purposes in a potential world-wide seismic surveillance system. An evaluation of the expected operational capabilities of the system has been carried out, using data recorded by the Very Long-Period Experiment network as a source. Conclusions from this evaluation and recommendations for future study are presented.
