Event Review with Jiggle

CUSP was finally retired as the event review system in the NCEMC in late November, 2006. CUSP was initially developed in Southern California during the late 1970s - early 1980s and has been used to time earthquakes for a number of years in Northern California. However, the CUSP system became increasingly outdated, as it relied on obsolete hardware. The primary responsibility for the programming and development necessary has rested on BSL staff. They implemented the RequestCardGenerator (a module that decides which channels to archive, given a particular earthquake), a waveform archiving module, and Jiggle (the earthquake timing interface) within the Northern California system. The entry of all parameteric earthquake data from realtime processing into the Oracle database and the preparation of station and instrument metadata for insertion into the database were important prerequisites for the transition. The NCEMC and SCMC collaborated on modifications to Jiggle for use in Northern California, such as the computation of $M_{d}$.
