A megatsunami is an extremely large tsunami wave generated by massive landslides or underwater earthquakes, where the wave height can be dramatically amplified by the shape of the surrounding terrain. In the Tracy Arm Fjord event, 64 million cubic meters of rock falling into the fjord created an initial wave over 100 meters high, which then climbed the steep rock walls like a ramp, reaching 481 meters—the second highest tsunami wave ever recorded in human history.

The wave reached 1,578 feet high. #tsunami #landslide #shortsAdded:
The impact was instantaneous and violent. The initial wave broke at over 100 m high, taller than the Statue of Liberty, and traveled down the fjord at more than 70 m/s. That is faster than a Formula 1 car at full speed, but that was just the first wave. What happened next was even more extreme. As the wave hit the opposing wall of the fjord, it climbed and climbed and kept climbing.
The steep rock walls of Tracy Arm acted like a ramp, channeling every jewel of energy from 64 million cubic meters of falling rock directly upward. The water reached 481 m, higher than the roof of the One World Trade Center, nearly 500 ft taller than the Eiffel Tower, the second highest tsunami wave ever recorded in human history.
