About Us


At Big Shaker Enterprises LLC we design, manufacture and operate the largest mobile earthquake simulators in the world.

Our simulators have been developed for earthquake preparedness education, training and consumer outreach. They are unique and provide the most realistic replications of earthquakes imaginable.

We are affiliated with companies including Ready America, QuakeHOLD! and QuakeHOLD! Industrial, all of which are leaders in earthquake preparedness and seismic fastening, and the experience we have gained from more than 20 years in business has gone into Big Shaker Enterprises.

The company has its headquarters, manufacturing and distribution warehouse in Escondido, California.

Our mission is to help the community in general understand the importance of being prepared, because preparedness is the best defense against earthquakes.
