neic-glass3

neic-glass3 is an open source and platform independent seismic event detection and association algorithm developed by the United States Geological Survey (USGS) National Earthquake Information Center (NEIC) and Caryl Erin Johnson, PhD, Introspective Systems LLC.

This algorithm converts a time series of seismic phase arrival times, back azimuth estimates from array beams, and cross-correlated detections into a catalog of earthquake detections at global, regional, and local distances. neic-glass3 is primarily intended for use as a continuous near real-time earthquake detector, however, it can also operate in a playback mode faster than real-time using queued data to support research and/or other seismic studies.

neic-glass3 is the third generation of the global association software used at the by the USGS to support the earthquake response and seismic data cataloging missions of the NEIC. This generation of the software was specifically developed to improve maintainability, portability, and regional/local capabilities.
