A future landslide-triggered tsunami in Greenland could be a lot bigger than experts first thought
People living in hamlets that were in the path of a 2017 tsunami have known all along that an even bigger wave could be in their future. New calculations suggest previous estimates of its size were too low.
When the tsunami triggered by the June 17, 2017 landslide in Greenland’s Karrat Fjord hit the hamlet of Nuugaatsiaq, it surged about 9 meters above the shoreline. That wave was so powerful that it washed 11 buildings out to sea, claiming the lives of four people. Nuugaatsiaq’s 84 residents were evacuated and the hamlet has been uninhabited ever since.
