We design, build, and operate Big Shakers, the WORLD’S LARGEST mobile earthquake simulators for education, training and consumer outreach.



Simulating up to magnitude 8.0 quakes, the Big Shakers have been used to train more than 30,000 people in California, Washington, Utah, and Nevada, by demonstrating how to prevent damage and injuries from happening during an earthquake.

If you don’t take earthquake preparedness seriously, you will after being in the Big Shaker and seeing firsthand what happens to unsecured household possessions.

• Damage to household possessions and personal injuries in an earthquake are predictable and preventable.

• Big Shaker simulations are the most realistic experiences you will get next to Mother Nature herself.

• The interior resemble a living room, complete with sofas, cabinets, and shelves.

• There is a pull-down ramp for easy handicap access for wheelchairs/the disabled.

• Big Shakers are designed and manufactured in the USA.
