Abstract

The Earthworm seismic processing system was first developed at the USGS Menlo Park, in collaboration with Carl Johnson, to produce an earthquake notification system. Since that development, a number of regional seismic networks have adopted the Earthworm system or created derivative networks: the NOAA-USGS CREST project has adopted the Earthworm architecture for its processing system; and the Council of National Seismic Systems has established an Advisory Board to guide further developments. Consequently, the USGS Earthworm team began joint efforts with a number of other institutions and individuals, resulting in a suite of new features for the Earthworm System. Other developments include the port of Earthworm to Windows NT, and Oracle/EW integration, and a module that produces record sections for web display.
