Who we are |
The mission of the California Integrated Seismic Network (CISN)
is to operate a reliable, modern, statewide system for
earthquake monitoring, research, archiving, and distribution
of information for the benefit of public safety, emergency
response, and loss mitigation. Further, the CISN seeks to
mitigate the impact of future earthquakes by collecting,
processing, and disseminating critical earthquake
information in a timely way.
- Who We Are
Six organizations have collaborated to form the CISN
in order to further the goals
of earthquake monitoring.
The founding members of the CISN include:
California Geological Survey,
Caltech Seismological Laboratory,
Berkeley Seismological Laboratory,
USGS Menlo Park,
USGS Pasadena, and the
California Governor's Office of Emergency Services.
In addition to the core members, several organizations
contribute data that enhances the capabilities of the CISN.
Contributing members of the CISN include:
University of California, Santa Barbara,
University of California, San Diego,
University of Nevada, Reno,
University of Washington,
California Department of Water Resources,
Lawrence Livermore National Lab,
Pacific Gas and Electric.
In November of 2000, the six institutions signed an MOA that
describes the CISN organizational goals, products, management, and
responsibilities of member organizations. The Steering
Committee oversees CISN projects while the external
Advisory Committee, representing the interests of
structural engineers, seismologists, emergency managers, industry, government,
and utilities, provides review. Other important CISN committees include:
documents and reports from the CISN are
available, including reports from the Program Management
Group; summaries of ANSS activities, documents from the
Standards Committee, and other useful materials.
To facilitate coordination of activities among institutions, the CISN has formed
three management centers:
The Northern and Southern California Earthquake Management Centers operate as twin
earthquake processing centers. The Engineering Earthquake Management Center has the
lead responsibility for producing engineering data products. More

The Federal Government through the USGS provides funds for
seismic monitoring in California both through internal and
external programs. These funds are used for core operations
of earthquake monitoring in southern and northern California.
The USGS office in Menlo Park works with UCB to maintain a
comprehensive program in northern California. The USGS
office in Pasadena is located on the Caltech campus and
the USGS share responsibilities with Caltech in operating
the seismic network in southern California. The USGS
external program also provides funds to Caltech, UCB,
and UCSD for operations and earthquake catalog production.
The USGS and NSF fund the Southern California Earthquake
Center (SCEC), which in turn provides funding for the
Southern California Earthquake Data Center (SCEDC) for
TriNet. The USGS through the Advanced National Seismic
System (ANSS) funds improvements in seismic instrumentation
throughout the state.
The State of California provides core funding for the
CGS/CSMIP program. The State, through the University
of California at Berkeley, provides core support for
the Berkeley Seismological Laboratory, including partial
support for the operation of the Berkeley Digital Seismic
Network. Recently, the State of California's Office of
Emergency Services provided significant funds to increase the
capability of the CISN. Funds are being used to support the
operation of TriNet in southern California, expand broadband
instrumentation throughout northern California, and increased
the number of strong motion instruments in urban
regions of northern California including the San Francisco Bay area.
