Swiss canton braces for tsunami

 

page11-nature_logoTHE land of chocolate and clocks could soon be known for something quite different: tsunamis. Authorities in Nidwalden, a canton in landlocked Switzerland, are factoring the risk of a tsunami in Lake Lucerne into their hazard plans. It is the first official acknowledgement of such a threat in Europe’s Alpine region — and comes in step with findings that the risk of tsunamis in the area, which is home to around 13 million people, is much higher than previously thought…

They dragged weighted nets across the seafloor and hoisted them up full of sole, plaice, and other bottom fish. But sometimes an enormous tusk would spill out and clatter onto the deck, or the remains of an aurochs, woolly rhino, or other extinct beast.
