Skip to comments.Tsunamis in the Alps? A killer wave slammed medieval Geneva, a new study says... [500 A.D.]

Nearly 1,500 years ago a massive flood in Geneva reportedly swept away everything in its path -- mills, houses, cattle, even entire churches.
Now researchers believe they've found the unlikely sounding culprit: a tsunami-like killer wave in the Alps. The threat, they add, may still be very much alive. (Video: Tsunamis 101.)
Spurred by a huge landslide, the medieval Lake Geneva "tsunami" (technically defined as a seismic ocean wave) swamped the city, which was already a trading hub, according to a new study.
Far from any ocean, the massive wave was likely generated by a massive landslide into the Rhone River, which feeds and flows through Lake Geneva, according to a group of Swiss researchers.
The team analyzed a massive sediment deposit at the bottom of the lake's easternmost corner and determined that the material had once sat above the lake and had slid all at once into the Rhone, near where the river flows into the eastern end of Lake Geneva (map).
The sudden splash sent a tsunami barreling down the length of the 225-square-mile (580-square-kilometer) lake toward Geneva, at the western end of the lake, the study suggests. Researchers estimate the wave was between 9 and 26 feet (3 and 8 meters) tall, depending on how quickly the rockfall occurred, which they were unable to measure.

This is an interesting theory.
Lake Geneva, regardless, remains one of the most beautiful vistas in the world.
Which it didn't but that's because they already knew back in the DeSoto's day that this could happen on that lake so NOBODY built really close to the shoreline ~ plus the lake used to have an uncontrolled height above sealevel and could change over night.
I'd guess Geneva was quite small when this 24 foot tsunami took it out!
Now will you take global warming seriously?! Chirps Al Gore.
A lot of people have felt that way about the Alps generally. :’)

Al Gore, upon reading this report, shouted out “Bush did it.”
Michael Moore is planning a movie also blaming Bush for this earth tsunami. Playing Bush will be Oliver Stoned. Playing the tsunami will be Roseanne Barr.
Playing the innocent Swiss milkgirl, Sandra Fluke.
Playing God will be Barack Obama.
Coming to an insane asylum near you, soon.
This thread has been a teachable moment for my 21 year old son, leading to a discussion about the Lituya Bay, AK tsunami in 1958.
Deep Purple musta cranked up the amps...
...water in the sky...
For the last time, I wasn’t involved! I know nothing of the events leading up to the creation of the tsunami.
Any alleged eyewitness accounts that I was seen surfing the tsunami are *clear* fabrications and not to be believed!
Tell it to the judge ya beach bum. Now come along quietly.

They aren’t so much lakes as they are freshwater inland seas. :’)
Because the water is fresh, it comes in something like 7/6ths faster, meaning that a series of waves will take a vessel apart faster on the Lakes than on the oceans and seas (everything else being equal of course).
Years ago I saw a family from south of the border somewhere walk toward the waterline in Grand Haven, staring at the water out to the horizon, and the dad put his hand down, cupped up some, tasted it, and said, basically, it isn’t salty. Foreign visitors are sometimes amazed. It’s weird to think that I take it all for granted — doesn’t everyone have something like this within an easy drive of their homes? :’)
I’ve often enjoyed swimming in wave conditions which probably weren’t safe, but I *always always always* avoid swimming by the piers. Besides unseen crap below the surface that can hook you, knock you cold, etc, the currents are much, much worse. Natural undertow is nothing by comparison.
The Edmund Fitzgerald had been the largest vessel ever on the Lakes, and nothing surpassed it for decades, probably due to economic factors.
Roman Geneva was originally founded as a border town to protect Gaul against the Helvetii. After the fall of the Empire it was absorbed into the Burgundian kingdom.
