Wind waves on Earth range in size from small ripples, to waves over 30 m (100 ft) high, being limited by wind speed, duration, fetch, and water depth.
What is the biggest wave ever?
An earthquake followed by a landslide in 1958 in Alaska’s Lituya Bay generated a wave 100 feet high, the tallest tsunami ever documented.

How big was the tsunami that killed the dinosaurs?
The impact did generate a massive tsunami and it was one of the largest waves Earth ever experienced. The asteroid that hit the Earth 66 million years ago was 8-10 km across and traveled from the northeast at a velocity of 20 kilometers per second which is 45,000 miles per hour (!)
