NSMP Project

• NSMP software written in 1992.

• Generates response and Fourier spectra, corrected acceleration, velocity, displacement

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

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.

The Parkfield Experience

• 50 SM stations within 20km

• 80% were SMA-1 recorders

• Wave field aliased

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
