Since Geneva and Lausanne are near by this article on Nature.com caught my eye. In addition to the local interest as aspect of the article - what is also interesting is the role of modern sensors, simulation and computer models to help determine evidence for historic reports that when combined give us insight for new developments in the region.
In ad 563, more than a century after the Romans gave up control of what is now Geneva, Switzerland, a deadly tsunami on Lake Geneva poured over the city walls. Originating from a rock fall where the River Rhône enters at the opposite end of the lake to Geneva, the tsunami destroyed surrounding villages, people and livestock, according to two known historical accounts. Researchers now report the first geological evidence from the lake to support these ancient accounts. The findings, published online in Nature Geoscience, suggest that the region would be wise to evaluate the risk today, with more than one million inhabitants living on the lake's shores, including 200,000 people in Geneva alone.
