The 1958 mega-tsunami in Alaska reached an amazing height of 1720 feet (524 meters.
It was higher than the Empire State Building in New York City!
Mega-tsunamis are very rare and mythical. As such, they are part of legends around the world.
The largest tsunami ever recorded on Earth occurred on July 9, 1958.
Its super wave reached 1720 feet (524 meters) and destroyed parts of Lituya Bay in Southeast Alaska.
This mega-tsunami was triggered by a strong 8.3 earthquake at the Fairweather Fault, which resulted in a huge landslide that fell into the narrow inlet of Lituya Bay.
The 30 million cubic metres of rock and ice caused a massive and sudden displacement of water, and formed this cataclysmic wave reaching incredible 1720 feet (524 meters).
