Earthquakes were recorded in London in 1247, 1275, 1382, 1439, 1626 and 1750. In 1580 the last significant quake struck, which originated in the Strait of Dover. This tremor was so large that people watched in fear as two men who were sitting on cannons at Tower Hill, were thrown to the ground. The church bells in the City were all set off, a pinnacle fell off Westminster Abbey, two children died when a chimney stack collapsed and Thomas Grey, a City cobbler was crushed by falling masonry in Newgate Street.
London is overdue a major earthquake and according to Dr Roger Musson, of the British Geological Survey, a quake measuring 6.0 on the Richter Scale could be caused by a slip in a fault line running from Dover to the Rhine region of Germany. Even though London is not on a fault line a quake can strike at any time. “All we can say is that something that has happened twice can, and probably will, happen three times.”
Now that the city is far more densely inhabited, fatalities would be higher and damage more extensive.
