A chance finding by a Swiss research team explain an event that happened centuries ago around Lake Geneva. In the sixth century Gregory of Tours, a chronicler of the Germanic people known as the Franks, told of an extraordinary event in what is now Switzerland, where the Rhone River spills into Lake Geneva. He wrote of a big rockfall in the year 563 AD in the vicinity of a place called Tauredunum. The debris plunged into the river, and a great mass of water 'overwhelmed with a sudden and violent flood all that was on the banks as far as the city of Geneva, more than 64 kilometres across the lake. The Geneva bridge was demolished, and several people inside the city walls of Geneva were killed. Historians and scientists have long believed that Gregory and another chronicler, Marius of Avenches, who told a similar tale, were describing a tsunami that raced across the lake. But there has not been any direct evidence of it until now.
