E-Defense

[2] Operated by the Japanese National Research Institute for Earth Science and Disaster Resilience (NIED),[3] it was the largest 3D earthquake shake table in the world when it was commissioned.

[3] Mitsubishi Heavy Industries machinery systems designed and constructed the facility,[10] which is located at Miki Earthquake Disaster Memorial Park.

After more accumulators were installed and bypass valves were added to the actuators, they achieved the goal of five minutes of sustained shaking.

[1]: 986  Most of the design and construction time for experiments takes place outside the main E-Defense facility to maximise the use of the table.

Experimental structures are placed onto the table using two cranes with a combined maximum loading capacity of 9000 kilonewtons.
