Advances in technology have made it possible to integrate separate earthquake monitoring networks into a single seismic system as well as to unify earthquake monitoring instrumentation. In California, this effort was first started under the TriNet Project in southern California, where Caltech, the then California Division of Mines and Geology, and the USGS combined their efforts to create a unified seismic system for southern California. With major funding provided by FEMA, OES, and the USGS, the TriNet project provided the opportunity to upgrade and expand the monitoring infrastructure, combining resources in federal, state, and university partnership. More recently, the integration effort was expanded to the entire State in a cooperation between the California Geological Survey, Caltech, UC Berkeley, USGS Menlo Park, and the USGS Pasadena called the California Integrated Seismic Network (CISN).
In the 2000-2001 Annual Report, we described the initial efforts to create this collaboration through the establishment of a memorandum of agreement and the development of the CISN strategic and implementation plans. The CISN is now in its fifth year of collaboration and its fourth year of funding from the California Governor's Office of Emergency Services.
