  1. Caltech/USGS Southern California Seismic Network Egill Hauksson, Caltech & Doug Given, USGS Pasadena CISN Meeting, Sacramento, 14 December 2011

  2. What we risk! • Not reporting on a major damaging earthquake • Making a gap in the continuous earthquake record • Rebuilding new CISN like infrastructure will be much more expensive • The partnerships of emergency responders, policy makers, and scientists may wither • Response & recovery may take longer than necessary • Ongoing training of the public and media may lapse

  3. Effects of Gradual Funding Cuts: • CISN T1-ring being decommissioned • Equipment upgrades are lagging • Decreased robustness in telemetry • Statewide exchange of data from stations • Software system updates lagging • Not attempted to implement statewide backup • Staff only “one deep”

  4. New Possible Investments with “other funds” • Replace obsolete “frame relay” data communications technology: • need Cal EMA to approve Caltech for GSA rates • Upgrade of sensor systems from TriNet era • Upgrade 1970s analog stations to contribute data to ShakeMap & EEW • New software systems for alarming, notification, & product tracking • New production versions of EEW software

  5. 1970s AnalogStations Upgrades
