The TriNet Project

Abstract

TriNet is a collaborative project of the California Institute of Technology, the California Division of Mines and Geology, and the U.S. Geological Survey to develop a digital seismographic network in southern California. TriNet will provide ground motion data having unprecedented frequency bandwidth and dynamic range throughout southern California, including urbanized areas. All stations will have 3- component, high-dynamic-range, strong-motion force balance accelerometers. Ill addition, all stations will have either real-time or dial-up digital telemetry. Many stations will have high-gain seismometers, many of which will be of the force-balance type with broad frequency responses. TriNet will enhance the traditional products of the existing regional seismographic network and strong-motion networks, and important new products will be developed. Major products of the TriNet project are: 1) near-real-time monitoring and cataloging of earthquakes in southern California, 2) broad-band ground motions from teleseismic earthquakes and other seismic sources, 3) strong-motion recordings from significant earthquakes, 4) near-real-time shaking intensity maps for emergency management, and 5) a pilot system for early warning of seismic shaking. Many other agencies (e.g., lifeline operators, emergency management agencies, etc.) are being included in the TriNet development.
