Salt Lake City, UT

What is the CISN?

• The California Integrated Seismic Network is a collaborative effort to integrate existing, separate California earthquake monitoring networks into a single statewide seismic monitoring system.

• The CISN provides the organizational framework to coordinate these earthquake-monitoring operations.

• The CISN constitutes the California region within Advanced National Seismic System (ANSS).

Who is the CISN?

• Core members have primary responsibility for the recording and monitoring of earthquakes and the creation of CISN products – California Geological Survey– U.C. Berkeley Seismological Laboratory– Caltech Seismological Laboratory– USGS Menlo Park– USGS Pasadena– USGS National Strong Motion Program

• Partnering member – California Office of Emergency Services

Who is the CISN?

• Participating members contribute to CISN activities through data exchange– UC Santa Barbara– UC San Diego– University of Nevada Reno– CA Department of Water Resources– Lawrence Livermore National Labs– Lawrence Berkeley National Labs– PG&E

CISN Goals

• Operate a reliable and robust statewide system to record earthquake ground motions over the relevant range of frequencies and shaking levels

• Distribute information about earthquakes rapidly after their occurrence for emergency response and public information

• Create an easily accessible archive of California earthquake data and information for engineering and seismological applications and research, including waveform data and derived products

Funding Sources

• Mixture of internal and external sources for each network:– USGS

– California Dept of Conservation

– California OES

– University of California

– Caltech

– Others

Statewide Monitoring

Focused UrbanMonitoring

Dual Data Transmission

• CGS CIT– 5 strong motion

stations in metropolitan Los Angeles region

• UCB CIT– 30 strong motion &

broadband stations statewide

– Goal to exchange 60 stations

CISN Backbone

• 5 dedicated T1 links operational 2002

• 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

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

Ongoing Development of CISN System• Alarm rules• Notification formats• Database Schemas• Continuous waveform

exchange• Strong motion

waveform exchange• Strong motion

amplitude exchange

• Magnitudes• Metadata exchange• Statewide association• Station naming

conventions• Archiving• Backbone operation• New software and

product development

How Does CISN Work?

• Memorandum of Understanding (est. Nov. 2000)– Internal organization: Project Management Group,

Steering Committee, Advisory Committee– Established agreement on goals and vision

• PMG and Standards Committees do the work– Meet by phone frequently, in person quarterly– Foster understanding of others’ problems – Resolution of problems improves all operations

• 5-year Strategic Plan– Updates vision, needs, and activities– Does not prioritize funding or schedule implementation

How Does CISN Really Work?

• At the start, participants could not see the benefits of collaboration

• Began to work together on common problems, seeking common solutions– Software, reliability, redundancy

• Key strategies to success– Use the capabilities in the group to get a critical mass

of resources – Build mutual confidence and reliance– Identify and work toward strategic needs– Minimize whining—it doesn’t work
