At Cambridge University eartquakes are modelled aboard the 10m diameter Beam Centrifuge. Recent advances include development of a new Stored Angular Momentum (SAM) actuator which can fire strong eathquakes at 100 gravities.
In addition to this, a new Mini Electro-Magnetic Earthquake Actuator was developed which can fire earthquakes of any desired frequency and duration. eal earthquakes, like the Kobe earthquake of 1995 can also be simulated in this actuator.
A new Equivalent Shear Beam (ESB) container is designed and manufactured to simulate the semi-infinite extent encountered in the field.
