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.
