  1. Brief history, Current Activities & ARRA Improvements David Oppenheimer – USGS Menlo Park

  2. What is the CISN? • The California Integrated Seismic Network is a collaborative effort to integrate existing, separate California earthquake monitoring networks into a single seismic monitoring system. • The CISN provides the organizational framework to coordinate these earthquake-monitoring operations. • The CISN constitutes the California region within Advanced National Seismic System (ANSS).

  3. Who is the CISN? • Core members have primary responsibility for the recording and monitoring of earthquakes and the creation of CISN products • California Geological Survey • U.C. Berkeley Seismological Laboratory • Caltech Seismological Laboratory • Menlo Park USGS • Pasadena USGS • USGS National Strong Motion Program

  4. Who is the CISN? Participating members contribute to CISN activities through data exchange. • UC Santa Barbara • UC San Diego • University of Nevada Reno • CA Department of Water Resources • Lawrence Livermore National Labs • Calpine • Cal Energy • Lawrence Berkeley National Labs • PG&E • Plate Boundary Observatory

  5. CISN Goals • Operate a reliable and robust statewide system to record earthquake ground motions over the relevant range of frequencies and shaking levels • Distribute information about earthquakes rapidly after their occurrence for emergency response and public information • Create an easily accessible archive of California earthquake data for engineering and seismological research, including waveform data and derived products

  6. Brief History • 11/2000 – core members sign MOA • 2000 – Initial ANSS funding • 2001 – Initial State funding • 2003 – NC begins adoption of TriNet software • 2003 – M6.5 San Simeon • 2004 – CISN Display released • 2004 – M6.0 Parkfield • 2008 – ANSS endorses AQMS software • 2008 – CESMD supersedes EDC • 2009 – CISN runs common software • 2010 - M7.2 Baja

  7. CISN Funding Total ~$16M

  8. 9% 12% 47% 10% 7% 15% CISN Expenditures Expenditures for California Seismic Monitoring Operate and maintain stations DataCenters Real-time operations and response Management Process improvement new products New/Upgraded stations

  9. Current Software Activities • Earthquake Early Warning • Metadata management • Improved exchange of data with CESMD • Station/Quake XML • Improved analyst review • Statewide ML analysis • National support of AQMS

  10. NetQuakes • 106 Instruments installed in NC; 50 more to be installed • Partnership with EBMUD for 7 dams • National support for 135 instruments • Siting Plan for 400 instruments in NC

  11. ARRA Upgrades • 48 dataloggers by UC Berkeley • 8 dataloggers by the NCSN

  12. The SCSN ARRA Project includes upgrades at 178 stations. As of 1 October 2010, we have completed work on more than 93 stations. • Cumulative histogram is shown below • White circles on the map represent stations that have been upgraded • Project completion date is 14 Sept. 2011 Datalogger & Sensor types Listed above
