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
Absolute magnitude Absolute magnitude Absolute magnitude is a measure of the luminosity of a celestial object, on a logarithmic astronomical magnitude scale. An object's absolute magnitude is defined to be equal to the apparent magnitude that the object would have if it were viewed from a distance of exactly 10 parsecs (32.6 light-years), with no extinction (or dimming) of its light due to absorption by interstellar dust particles. By hypothetically placing all objects at a standard reference distance from the observer, their luminosities can be directly compared on a magnitude scale. As with all astronomical magnitudes, the absolute magnitude can be specified
