  1. ANSS Interaction andNetQuakes Update David Oppenheimer U.S.G.S Menlo Park CISN Steering and Advisory Committees 28 January 2008

  2. NSMP Project • NSMP software written in 1992. • Generates response and Fourier spectra, corrected acceleration, velocity, displacement

  3. NSMP Project • BAP uses file-based I/O and configuration • 2-byte precision output and therefore duplicated at CESMD • Poor interface to ANSS data • NSMP project recently reorganized • Data acquisition/processing in NCSN • Field installation/maintenance in Earthquake Effects Project

  4. Goals • Migrate NSMP post-processing algorithms into CISN software architecture with effective user-interface tools • Provide a supported, stable, and efficient processing platform for generating processed strong-motion records. • Ensure that migrated software is capable of meeting present and future needs of ANSS, NSMP and the COSMOS user community.

  5. The Parkfield Experience • 50 SM stations within 20km • 80% were SMA-1 recorders • Wave field aliased

  6. San Fernando CISN & ANSS TriNet Number/Yr 3600 more stations needed to achieve Vision 2005 goal of 5500 stations It will take ~70 years at this rate

  8. Flash Memory >36-hour Sealed Lead Acid Battery Colibrys SF2005S ±3-g MEMS accelerometers Three 1000sps Burr-Brown (TI) ADCs

  9. Threaded rods GPS Power Wireless Console Ethernet Ethernet

  10. Securing screws Padlock hole

  11. M3.1 2009/01/22 20:46:58  recorded at CI.GSA (40km) CI HNZ 0.34 NQ HNE 0.42 HNN 0.41 Seconds

  12. Software Status: SeisNetWatch Server Functional

  13. Software Status: Registration Page Functional

  14. Project Status • 3 Servers operating in Menlo Park, Golden, and Caltech • Peak ground motions fed into CISN system • Waveform images created dynamically and available on USGS web server • SOH fed into SNW • 33 units delivered; 25 more to be delivered soon • 2 each sent to cooperating RSNs • 16 to be deployed in SF Bay region; 33 volunteers • 5-year/$3M IDIQ in place
