Focused UrbanMonitoring

• CGS CIT– 5 strong motion

stations in metropolitan Los Angeles region

• UCB CIT– 30 strong motion &

broadband stations statewide

– Goal to exchange 60 stations

Dual Data Transmission

CISN Backbone

• 5 dedicated T1 links• Auto-failover to

Internet via IP tunnels• Monitoring/alarming

software operational• Networks now

exchanging CISN seismic data

Integration and Standardization

• Real and near real-time integration of parametric and waveform data from 13 seismic networks– PG&E as of 8/17/2006

– Calpine soon?

• Developing software to integrate of CGS, CI/USGS, NCSN, and UCB real-time systems

Progress toward Statewide Monitoring

through

CISN Software

• Melding of many complex systems– Earthworm front-end

– TriNet back-end

– NCEDC/SCEDC data archiving

– Java, C, C++, Perl, SQL, Fortran, Solaris, Windows, Oracle, etc..

• Same software across CISN means:– Same configurations,

same products

– Full parametric exchange

– All waveforms used (including NSMP, CGS)

– New methods easier to implement

– Failover behavior can be

modeled and understood

• Code is now developed by all partners– An example of how CISN works well

– An example of how CISN doesn’t work well

SCSN: RT system

NC ≠ SC

• Network split across the SF Bay– Requirement for robust

operation if one half fails• Different systems

– Field hardware– Telemetry– Institutions– Software

• Cannot compute ML for all quakes

Menlo Park Berkeley

Required development for NC implementation

• Replaced proprietary messaging software with CMS software

• Implementation of “location” codes (statewide)

• Station metadata• Proxy waveserver• Implementation of Md in

Trinet software• ML calibration (statewide)• Testing, testing, testing

NCSS Software Transition Status

• Post-processing– Prototype functional as

of July, 2006

– Md implemented and Q/C’ed

– SNC → SNCL ready

– Testing and training

– 10/15/2006 switch

• Real-time processing– After post-processing

switch

– Conversion of alarming software

– New quick-review

– Testing

– 12/31/2006 switch

CISN: Statewide Version 1.0• Will rely on three real-time services:

– Continuous “reduced” amplitude exchange

– “Pick” exchange– Proxy waveserver for post-processing

• Real-time alarming– NC and SC will each alarm for their

authoritative box for M<4.0 and statewide for M≥4.0.

– The QDM filter will post the first solution, which in some cases may be superseded by the authoritative solution, or possibly NEIC.

• Statewide ShakeMap– Produce statewide ShakeMap at three

centers (PAS, MP/BK, and CGS). – Operate one statewide web portal for

ShakeMap• Post-Processing and Archiving

– Each center (PAS and MP/BK) will post-process and archive parameters and waveforms in it's region of responsibility.

– CGS will post-process and distribute SM data and engineering quick reports.

• Timeline: Prototype by 30 June 2007

Budget

and

Funding

• The CISN Strategic Plan goals were established for the level of funding that we anticipated in 2001.

• At its inception in 2001 the CISN asked OES for $6.6M per year. – This funding was cut to and has remained at the $2.4M

per year for the last three years. • Full ANSS funding expected in 2001 and

subsequent years has not occurred. – level-funding for CIT, UCB, and USGS NCSN/SCSN

and NSMP network operations for the last three years
