CISN:California Integrated Seismic Network • The Program Management Group (PMG): • Tony Shakal –CGS • David Oppenheimer –USGS Menlo Park • Peggy Hellweg & Doug Neuhauser – UC Berkeley • Egill Hauksson - Caltech • Doug Given –USGS Pasadena CISN Advisory Meeting Jan. 28, 2009
CISN Goals • Operate a reliable and robust statewide systemto record earthquake ground motions over the relevant range of frequencies and shaking levels • Rapidly distribute informationabout earthquakes after their occurrence for emergency response and public information • Create an easily accessible archiveof California earthquake data for engineering and seismological research, including waveform data and derived products • Develop new algorithmsfor analyzing earthquake data and creating new user products by applying the latest research and technological discoveries. (from Strategic Plan)
