2007 Kent earthquake earthquake in 1950. The strongest recorded British earthquake is the 1931 Dogger Bank earthquake, which measured 6.1 on the Richter scale. Ten months later, the earthquake's strength was surpassed by that of the 2008 Lincolnshire earthquake, which was 5.2 in magnitude. Less than two years later, on 3 March 2009 at 14.35 UTC, Folkestone was shaken by a smaller magnitude 3.0 quake, located in the same area. 2007 Kent earthquake The 2007 Kent earthquake registered 4.3 on the Richter scale and struck south east Kent, South East England on 28 April 2007 at 07:18:12 UTC (08:18:12 local time), at a
Richter magnitude scale distance of the station, formula_23. In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the formula_2 value. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to approximately a doubling of the energy released. Events with magnitudes greater than 4.5 are strong enough to be recorded by a seismograph anywhere in the world, so
