CISN Goals

• Operate a reliable and robust statewide system
  to record earthquake ground motions over the
  relevant range of frequencies and shaking levels
• Rapidly distribute information about earthquakes
  after their occurrence for emergency response and
  public information
• Create an easily accessible archive of
  California earthquake data for engineering and
  seismological research, including waveform data
  and derived products
• Develop new algorithms for analyzing earthquake
  data and creating new user products by applying
  the latest research and technological
  discoveries.
