  • Faking quakes at full scale: Giant shake tables simulate

    Shake tables are, at their most basic, essentially just platforms that can be vibrated in a controlled and regular manner. The first known shake table was developed in Japan in the late 19th century and was driven by hand. Subsequent innovations included mechanical devices like springs, swinging pendulums and eccentric-mass-weighted wheels.
