Mill Park (3239.5 km WSW of epicenter) [Map] / Light shaking (MMI IV) / rattling, vibrating / 15-20 s : The intensity was somewhat weak as I did not know it was an earthquake at first (I thought we had strong winds). The windows rattled and the floor vibrated for around 20 seconds, so we hid under the table until it stopped.

'Shaking table' research protects UK from earthquake ...

This testing involves Bristol's 'shaking table', which at 3x3m is the largest in the UK. It can carry up to 15 tonnes and reach acceleration of up to 5g, with maximum displacements of 0.15m. Researchers input different settings to the table, simulating earthquakes up to 7.2 on the Richter scale – the UK's strongest ever quake was 6.1.
