Nidwalden

The crash occurred shortly after another small plane crashed into the Swiss Alps, in the canton of Nidwalden, killing a family of four on board.

Nidwalden, which borders the lake, has now commissioned Anselmetti’s team to assess the likelihood of such an event for different scenarios, including earthquakes of various strengths or a rockslide — as well as the probable effect on the surrounding land.

Nidwalden is, for now, blazing a lonely trail with such plans.

Authorities in Nidwalden, a canton in landlocked Switzerland, are factoring the risk of a tsunami in Lake Lucerne into their hazard plans.

Other regions may yet follow in Nidwalden’s footsteps.
