Abstract :
The development of techniques for detecting and locating the sources of seismic events as well as discriminating phases in the coda of these events is reported. The work continues an effort to detect, locate, and discriminate regional seismic events. The algorithms were originally developed on SUN workstations and are currently being implemented on a real-time system based on the TMS320C30 DSP chip. The original motivation was to use seismic information to verify compliance with respect to a comprehensive test ban treaty, but the algorithms could be used for monitoring nonproliferation treaties. The signal processing algorithms can also be applied in the analysis of seismic data in general
