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

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”

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
