The UK 's coastal areas and infrastructure are under increasing risk from tsunamis , with a new study showing that Britain has been hit by huge waves at a significantly higher and more intense frequency than previously thought . The waves could devastate coastal installations , ports and power stations , it warns . Such waves, they suggest, pose a serious threat to coastal installations such as nuclear power stations, ports and oil terminals, as well as towns. Although the UK has never been considered to be at serious threat from a tidal wave , which is normally caused by earthquakes , new evidence shows that underwater waves are causing billions of tonnes of mud to shift from the sea bed , which is producing waves beneath the surface .
