Tsunamis are among the most destructive forces known to Man, but most of us in Britain think they are one thing we don't need to worry about. Professors Simon Haslett and Ted Bryant have already challenged this view with their belief that the Bristol Channel flood of 1607, one of Britain's greatest natural disasters, was in fact a tsunami. But the story doesn't stop there. In Britain's Forgotten Floods, Simon and Ted investigate evidence for what they believe are at least four more British tsunamis.

Joining them on their journey around the British coastline is historian and scientist Vanessa Collingridge, presenter of Radio 4's Making History. Vanessa will be weighing up the evidence, and also looking back to the Lisbon tsunami of 1755, an almost forgotten disaster that had a profound effect on Britain, and changed the course of European history.
