More Details on Shake Test

I just passed some email with Jud Cooley, Director of Engineering for Project Blackbox (and one of the co-stars of the Project Blackbox Shake Test Video). The earthquake that the team simulated was the Northridge Earthquake that occurred on January 17, 1994 outside of Los Angeles. This earthquake had a magnitude of 6.7 on the Richter Scale.

To simulate the quake, the team used about 1.7G of lateral shock.

The team also did additional testing of up to 2.0G using sawtooth waves. These are worse than the rolls of the earthquake simulation.
