Technical Drill Resources

Simulated earthquake mapping software, ShakeOut documentation and animations, ShakeOut earthquake and aftershock shakemaps, and other information resources for advanced drills.

CISN Display

A real-time simulation of the CISN Display tool has been created for use in the ShakeOut Drill. Download this application prior to November 13. At approximately 10 a.m. on November 13, the ShakeOut earthquake data (7.8 magnitude earthquake, 17,500+ aftershocks over a week-long sequence, and shakemaps) will start showing up on the CISN Simulation much like the real version performs.

  • Available for the ShakeOut Drill on November 13 at 10am thru November 20 at 9:56am. Data will begin appearing on the screen when the drill begins:
    • ShakeOut Scenario earthquake locations, occurrence times, magnitudes (for a magnitude 7.8 main shock and aftershocks)
    • Epicenter maps
    • Intensity ShakeMaps for the magnitude 7.8 and the largest aftershocks
  • To download the CISN Display for ShakeOut application, go to then click on "To download the ShakeOut Simulation, click here" under the ShakeOut banner.
  • Any questions, contact Margaret Vinci at
