The Tauredunum event in the year 563 was a tsunami in Lake Geneva, which was triggered by a massive landslide and widespread destruction caused, many people came along the lakeshore to death. After two contemporary reports ( Gregory of Tours and Marius of Avenches ) the disaster by the slipping of a mountain slope was caused at a place called Tauredunum at the eastern end of Lake Geneva. There was a big wave that spread along the lake, where they swept the villages on the shore and the city of Geneva met with such force that they spilled over the walls, killing many inhabitants. The shaft should still have been eight feet tall in Geneva.

It is also possible that the first landslide of the Rhone about 5 km above its confluence with Lake Geneva dammed and later broke this barrier, and then the tsunami came.

A study that was published in October 2012, suggests that the Tauredunum landslide slipping of the sediments caused that had accumulated at the point where the Rhone empties into Lake Geneva. This caused a huge underwater mudslide that moved more than 100 million cubic meters of sediment and a tsunami caused, which was up to 16 m high, and the city of Geneva reached in about 70 minutes. There is evidence of four previous mudslides, suggesting that tsunamis may be a recurring phenomenon on Lake Geneva.
