Earthworm-based automatic system for real-time calculation of local earthquake source parameters

Resumo

Experience in introduction of an automatic system of earthquake source parameter calculation based on an existing seismic network is described. Open source software products for automatic seismic data processing are reviewed. Methods for real-time waveform stream processing are discussed in detail. Parameters of some subroutines of the system are described. Information flows and data life cycle in the developed automatic system are outlined. Earthquake location errors in the system are analyzed. The detection capability of seismic networks is evaluated.
