The Killer Wave of 1607 (2005)

On January 20, 1607, a colossal wave struck the Bristol Channel, striking without warning and causing widespread destruction. The floodwaters reached as far inland as Glastonbury Tor, inundating 200 square miles of Somerset, Devon, Glamorganshire, and Monmouthshire, and claiming up to 2,000 lives. For four centuries, this devastating event has been largely forgotten. Now, Timewatch revisits the terror of 1607, documenting the human tragedy and following two scientists who become convinced the wave was not an isolated storm, but a tsunami.
