A massive landslide occurred in the Taan Fjord of Icy Bay in Wrangell-St Elias National Park, Alaska on October 17, 2015. The event generated a local mega-tsunami that sheared trees at an elevation of more than 500 feet (152.4 meters) on a peninsula within the fjord. Another massive landslide occurred in Glacier Bay National Park on June 28, 2016. Events such as this happen maybe three to five times per year around the world, and Southeast Alaska is the global hotspot. Read more here and here.
