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

• Partnering member
– California Office of Emergency Services
Who is the CISN?
• Participating members contribute to CISN
activities through data exchange

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:

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

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
