А вот что было на самом деле:
An earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented. When the wave ran ashore, it snapped trees 1,700 feet upslope. Five deaths were recorded, but property damage was minimal because there were few cities or towns nearby.
То есть волна была тридцатиметровая, но взлезла по склону до высоты аж 525 метров.
З.Ы. Похоже, я был неправ.
