SCSN has a suite of software products in use, many of which assist in the location, magnitude, and ShakeMap generation. These software products have mostly been designed by Caltech and USGS staff, save for a few particular software products created by outside private contractors. ITSI has assisted in creating SeisNetWatch, a product designed to monitor the entire Southern California Seismic Network in near real-time. Each station is assigned a color value based on the health of that particular station (Green=good, Yellow=moderate, Red\=poor). If problems with the station arise, such as data latency due to telemetry, clock quality, mass position, voltage, sequence errors, datalogger state, number of packets, or noise variance, the color will change from green to yellow or from yellow to red. This enables the on-call Duty Operator to investigate the issue, and either open a trouble ticket with the telco or dispatch the SCSN field techs.

Another useful software package designed by ITSI is the California Integrated Seismic Network Display (CISN Display), or commonly called QuakeWatch. The CISN Display is a Java-based program that is independent of the OS platform. CISN Display can run on Widows, Mac, Unix/FreeBSD, Sun Solaris, and Linux. The program has been released for beta test to SCSN critical users.
