"Has the Structural Integrity of The Channel Tunnel Always Been Compromised?"

Quote: ""Recently, an earthquake occurred along the English Channel
coast, with its epicentre at Folkestone in Kent, at
8.28 a.m. (local time) on 28 April 2007. The local earthquake
magnitude was estimated by the British Geological Survey
as 4.2ML (Walker and Musson, 2007) and no discernable
affect was reported on the sea. However, worryingly, a local
news outlet reported that coastal residents on feeling the
tremor “started rushing out from their houses and on to the
beach for safety” (Kent News, 2007)! This highlights the
need to assess the threat from tsunami and associated hazards
in Britain and, if appropriate, raise public awareness of
the potential hazards."

According to "The Natural Hazards and Earth System Sciences Organisation" (go to.... http://www.nat-hazards-earth-syst-sci.net/8/587/2008/nhess-8-587-2008.pdf ), siesmic events either in or on either side of The Channel are historically far from rare!

"I tell you naught for your comfort, Yea naught for your desire, Save that the sky grows darker yet, And the sea rises higher." - GK Chesterton

"..a 2005 BBC2 Timewatch documentary which was postponed and re-edited after the Asian tsunami due to its sudden topicality. It documented how, out of a clear blue sky on 30th January 1607, nearly 600 km of the Devon, Somerset and Welsh coast was inundated by a wave of up to 7.5m (25ft). The ‘largest and most destructive flood in British history’ , it may have been caused by a tsunami deriving from an undersea quake, the wave reaching up to 14 miles inland (to the foot of Glastonbury Tor), leaving a temporary inland sea of over 200 square miles for ten days, and drowning around 2,000. For the benefit of sceptics, the academic study the documentary was based on pointed out a 1755 seaquake off Portugal had sent out a 15m (49ft) high tsunami that killed nearly 50,000. There has also been a claim a tsunami hit Dorset in 1868 – luckily the relatively deserted stretch of shore west of Portland."
