Cornwall's Tsunami Risk
3:22pm 17th July 2013
Parts of Cornwall could be wiped out by a 3m high tsunami, if there is ever an earthquake off the coast of Portugal.
An emergency planning meeting has looked at the last wall of water to hit our shores, which was back in 1755.
Experts admit the chances of it happening again are small, but say there is no contingency plan in place and they need to do more research.
Fowey harbour master Paul Thomas said: "The geography of Cornwall is different. A tsunami wave becomes dangerous when it reaches shallow water and gets higher and higher as it's energy can't disperse. It would affect different shorelines differently.
"The threat, of course, is one a beautiful day like this where you see Fowey flat-calm, full of people enjoying the river and if an unexpected wave were to arrive now, then obviously there's all that sort of physical effect of capsizing boats and craft and all the people who are on the water."
