California Integrated Seismic Network: Monitoring and Rapid Response

CISN operates a statewide system to record earthquake ground motions, distribute information rapidly after earthquakes, and create an accessible archive of earthquake data. The network also develops new algorithms for analyzing earthquake data and creating user products.

Presentation Transcript

  1. 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

  2. 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)

  3. Who is the CISN? • Core members • USGS (Pasadena & Menlo Park) • Caltech • UC Berkeley • Calif. Geological Survey (CSMIP) • Calif. Office of Emergency Services • Participating entities(real-time data contributors) • UC San Diego • UC Santa Barbara • University of Nevada Reno • Calif. Dept. of Water Resources • Lawrence Livermore National Labs • Lawrence Berkeley National Labs • PG&E • EarthScope - US Array/PBO • Calpine • CalElectric

  4. CISN is One of the 7 ANSS Regions Alaska PacificNorthwest Northeast Inter-MountainWest Mid-America California Hawaii

  5. CISN Statewide Monitoring

  6. New Broadband stations 2 USArray stations retained 5 Upgraded stations 6 Newly telemetered stations 6 Newly imported stations CalEnergy (EN) 8 PG&E (PG) 4 Stations: New & Upgraded(since our last meeting)

  7. Three Rotational Seismometers • Millikan Library (2) and Garner Valley • Eentec R-1 triaxial rotational velocity sensors • 0.05 – 20/50 Hz bandwidth • 50V per radian/sec • ~0.1 radian/sec clip Hector Mine aftershock Mw 5.1

  8. MHDP: Southern San Andreas Build-out • 20km spacing • BB, SM, GPS • 11 new sites • 6 upgraded sites • low data latency • on-site computer CI.SNO

  9. CISN Software SystemFY 2008 Accomplishments • Leap second compliance finished • All code in SVN repository • TRAC documentation begun • Reference system completed • Many improvements & bug fixes

  10. CISN Software Status FY 2008 Accomplishments • Northern California center • post processing done, real-time soon • Southern California center • In process of upgrade to leap-second version • Other ANSS regional networks • running at HVO • will be installed at UW and UU this year • CERI & LDEO this year or next

  11. Other Accomplishments • Continuing support of Earthquake Early Warning • Statewide ML calibration • Handled Alum Rock & Chino Hills (Mw 5.4s) • Helped NESMP converted 90 channel Factor Building Array to USGS operation • CIT hosted ANSS NetOps workshop • Participated in ShakeOut

  12. Other Developments • ANSS Network performance standards • NSMP free-field site adoption • ANSS Waveform Archive – RFP is open • Metadata Repository in Golden • Seismic equipment depot at ASL

  13. Last Year’s Action Items • Modify MOU to alloy chair 3rd term. – Done • PMG to document Japanese EEW spending. • $500M initial, $23M/yr + $120M upgrade/10yr • Document steps toward EEW • Draft EEW plan done • Address ShakeMap issues • Provide talking points for Dick McCarthy’s trip to Japan. - Done

  14. Hasta la vista, baby!
