The CISN is dedicated to improving seismic monitoring through statewide coordination, robust operation, rapid and reliable earthquake reporting, and seamless access to earthquake and engineering strong-motion information archives. The 5 founding (core) institutional members are the California Division of Mines and Geology, Caltech, UC Berkeley, USGS-Menlo Park, and USGS-Pasadena, but other institutions engaged in seismic monitoring in California are invited to join. The California Governor's Office of Emergency Services (OES) serves as an ex-officio participant in the CISN. The core institutions and OES have signed an MOA that describes the CISN organizational goals, products, management, responsibilities of member organizations, and locations of operations and data centers. The CISN Steering committee has selected an Advisory committee representing the interests of structural engineers, seismologists, emergency managers, industry, government, and utilities. It has also formed a Program Management Group to address planning and coordination and a Standards committee to resolve technical design and implementation issues. The CISN is coordinating its development with similar efforts in the ANSS. In 2000 and 2001, the CISN institutions coordinated on the siting of 70 new ANSS-funded stations in the San Francisco Bay region and over 150 TriNet-funded stations in southern California. Peak ground motion data recorded on these and similar instruments operated by the CISN partners are now routinely used to construct ShakeMaps in near real-time for all of California.
