Routine analysis of the data produced by BSL networks begins as the waveforms are acquired by computers at UC Berkeley, and ranges from automatic processing for earthquake response to analyst review for earthquake catalogs and quality control.
Starting in the mid 1990s, the BSL invested in the development of the hardware and software necessary for an automated earthquake notification system (Gee et al., 1996; 2003a) called the Rapid Earthquake Data Integration (REDI) project. This system provides rapid determination of earthquake parameters: near real-time locations and magnitudes of northern and central California earthquakes, estimates of the rupture characteristics and the distribution of ground shaking following significant earthquakes, and tools for the rapid assessment of damage and estimation of loss. In 1996, the BSL and USGS began collaborating on a joint notification system for northern and central California earthquakes. This system merges the programs in Menlo Park and Berkeley into a single earthquake notification system, combining data from the NCSN and the BDSN. Today, the joint BSL and USGS system forms the Northern California Earthquake Management Center (NCEMC) of the California Integrated Seismic Network (Section 3.2.), and development is proceeding on the next generation of earthquake reporting software based on Southern California's Trinet system.
With partial support from the USGS, the BSL has also embarked on the development and assessment of a system to warn of imminent ground shaking in the seconds after an earthquake has initiated but before strong motion begins at sites that may be damaged (Research Study 2.17.).
