Routine earthquake analysis in Northern California has been
unified since June 2009, with mirrored systems at the BSL and at
the USGS in Menlo Park (see Operational Section 2). Processing
begins as the waveforms arrive at the computers operating the
real-time software, or AQMS software, and ranges from automatic
processing for earthquake response to analyst review for
earthquake catalogs and quality control. In the mid 1990s, the
BSL developed an automated earthquake notification system (Gee
et al., 1996; 2003a) called Rapid Earthquake Data Integration
(REDI). This system determined earthquake parameters rapidly,
producing 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. Then, in 1996, a collaboration
began between the BSL and the USGS for reporting on Northern and
Central California earthq
