The earliest scientific studies of earthquakes in the late nineteenth century concentrated on capturing the precise movement that was experienced by an object in an earthquake; however, these did not include accelerations or forces. The first shaking table used to study the response of a brick column to repeated horizontal movements was made in Tokyo in around 1890 by the British engineer John Milne. Early experiments in California tended to focus on the liquefaction of soil in earthquakes that led to many building collapses. The dynamic response of buildings to earthquakes was first studied in depth in the 1930s by Lydik Jacobsen and his pupil John Blume. The most sophisticated study from this time was on a 1:30 scale model of a 15‐storey building, each storey of which had five degrees of freedom – two horizontal, one vertical and two rotational. In the 1930s Arthur Ruge at MIT developed the first shaking table that was moved using hydraulic actuators driven by signals recorded during an actual earthquake. This provided a more realistic movement than the regular horizontal sinusoidal oscillation of earlier tables.
