Correspondingly, why do tsunamis go unnoticed at sea?

A tsunami is not a sub-surface event in the deep ocean; it simply has a much smaller amplitude (wave heights) offshore, and a very long wavelength (often hundreds of kilometres long), which is why they generally pass unnoticed at sea, forming only a passing "hump" in the ocean.

Tornado consists of very powerful winds, and a violent tornado can travel with the speed of 300 km/h. How tall can tsunamis get? Tsunamis generally reach a maximum vertical height onshore, called a run-up height, of no more than 100 feet above sea level. A notable exception was the 1958 tsunami triggered by a landslide in a narrow bay on Alaska's coast. Its over 1,700-foot wave was the largest ever recorded for a tsunami.
